DESCRIPTION

Context and Objectives

Theoretical evaluation of the performance of nanoelectronic (especially spintronic) systems is essential for determining their optimal operating points and for their integration into information processing architectures. The classical approach is to use intensive numerical simulations, but their complexity usually prevents their exploitation in the analysis of nanotechnological information processing architectures. The first objective of this project will be to combine the expertise in spintronics and nanotechnology within the Institut Jean-Lamour (IJL, Nancy, France) and the skills in modeling complex systems of the LMOPS Laboratory (Metz, France) for the development of new methods based on the analysis of large volumes of data (i.e., Data Mining) and statistical learning (i.e., Machine learning) for the establishment of physical models of low algorithmic complexity for the prediction of the dynamic behavior of complex spintronic systems, more specifically systems currently developed with the Institut Jean-Lamour. The second objective will be to exploit these data-driven models for the analysis of spintronic architectures in (i) physical cryptography and (ii) hardware artificial intelligence.

Candidate profile

The post-doctoral candidate needs a Ph.D. in Physics or a related field with, if a possible, a concentration in Solid State Physics / Spintronics The candidate must have at least two of the following skills: (i) background in spintronics systems (ii) advanced knowledge in numerical simulation techniques (e.g., micro-magnetic simulations) (iii) high proficiency in Matlab and/or python for advanced modeling and data analysis. Knowledge of concepts related to complex physical systems is recommended but not mandatory. Knowledge of basic machine learning concepts (e.g., recurrent neural network, etc.) will help immediately be operational on the project but is not mandatory. A previous experience in the field of spintronics and/or reservoir computing will be also highly appreciated but is not compulsory. Expected qualities for the candidate: creativity, autonomy, scientific rigor, agility in tackling interdisciplinary topics, strong programming skills, and the willingness to work in a team. Proficiency in English speaking and writing is mandatory; French is optional, although welcomed.


Research environment

The post-doctoral candidate will be part of two vibrant interdisciplinary research teams. The first research team is within the Institut Jean-Lamour (IJL) located in the heart of Artem (Arts and technology) Campus in Nancy. The second team is within the Chair in Photonics / LMOPS laboratory located in a technological cluster of universities and research centers in Metz. State-of-the-art research/measurement equipment in spintronics and computing (including access to a supercomputer for simulations will be made available by the two laboratories. In addition to their core scientific objectives, the candidate will actively exchange with researchers engaged in ANR project (MARIN) at IJL and will also have scientific exchange with collaborating laboratories such as the C2N (Paris-Saclay) to consolidate a collective effort on the development of novel spintronic-based architecture for information processing. The recruited person will present their results at international conferences and will have the freedom also to explore different ideas and concepts in the framework of this Lorraine University of Excellence (LUE) postdoctoral fellowship.

Complex oxides attract an increasing interest driven by their wide range of physical properties and the opportunity to functionalize them in nanometric heterostructures for new electronic devices. One can especially mention Rare Earth (RE) vanadates and nickelates based nanosystems in which novel properties (resp. mutiferroïcity and superconductivity) can emerge via the design of interfaces at atomic level in artificial
architectures.

In RE vanadates-based nanosystems, ab initio calculations namely predict (i) the emergence of hybrid improper ferroelectricity in layered structures combining different cations, and (ii) the coupling of the polarization to Jahn-Teller distortions leading to a direct and strong coupling between polarization and magnetism. RE Nickelates recently rose a considerable enthusiasm in the scientific community with the discovery of superconducting properties in Sr-doped RENiO2 compounds as thin films. Many studies have been launched to analyze and investigate the possible underlying physical mechanisms in comparison with high Tc cuprates materials. In both RE vanadates and RE nickelates based systems, the emergence, understanding and control of these novel properties require the ultimate control of the interfaces and of the atomic planes stacking. Expected/observed phenomena are namely highly sensitive to fine details of structural/interface properties.

Objective

Our objective is to explore these phenomena by: (i) the synthesis of a multiferroic material in combining strains and interfaces engineering in AVO3/A’VO3 superlattices (ii) the synthesis of new Ni-based superconducting materials in tailoring the atomic planes stacking in the Ruddlesden-Popper serie of RE nickelates. For this purpose, a state of the art instrument for the synthesis of complex oxide is installed at the Institut Jean Lamour, as part of the Daυm equipment (Ultra High Vacuum interconnection of synthesis and insitu analysis tools). This Molecular Beam Epitaxy chamber (DCA), equipped with an ozone generator, enables us to achieve the epitaxial growth with an ultimate control of the atomic arrangement (Atomic Layer by Layer growth) and thus to design complex and artificial architectures at the nanometric scale.

Work context

The post-doctoral researcher will work at the Institut Jean Lamour (IJL, ijl.univ-lorraine.fr) in the SPIN team (spin.ijl.cnrs.fr), composed of 15 permanent staff and about 20 PhD and post-doctoral students. In this stimulating environment, internationally recognized for its expertise in materials design, nanomagnetism and spintronics, he/she will work at the design and elaboration of the vanadates and nickelates based-systems by using ALL-MBE and benefiting from other in-situ available analysis (RHEED, XPS, ARPES…). He/she will be in charge of the full structural characterization (X-ray diffraction, electronic microscopy) and of the investigation of magnetic/electronic transport properties in using state-of-the-art instruments of the dedicated Competence Centers at IJL.

A new field is emerging which combines ultra fast optics, nanomagnetism and spin electronics. It will open new possibilities for ultrafast low-dissipative manipulation and transport of information. The UltraFast Opto-magneto-spintronics for Future Nanotechnologies (UFO) project has been funded by the ANR. In this project, ultrafast laser will be used to generate hot electron pulses. The Sub picosecond hot electron pulses will then enable the manipulation of spin and magnetization in spintronic devices (1). A strong consortium will tackle this project: the team at IJL showed that not only ferrimagnetic alloys but also ferromagnetic multilayers and granular media can be switched by sub picosecond laser pulses (2). They also demonstrated very recently for the first time that (sub)picosecond electron pulses can generate ultrafast magnetization switching (3,4). On the other hand the team at SPINTEC has a long and internationally recognized experience in the field of spintronics and its applications. Finally, the team at LPCT is expert in ab initio calculations, in particular density functional theory.

The objectives of the post-doc can be summarized as follow:

– Provide a fundamental understanding of the interaction between ultra-short (polarised) pulses of light, spin polarised current and magnetic objects especially at the nanometer length scale and femto-second time scale in engineered spintronic devices;

– Demonstrate that magnetization and polarized current can be manipulated in spintronic devices such as a magnetic SOT-Hall cross, spin-valves and tunnel junctions with the help of polarized light;

– Fabricate spintronic devices (memory cells and logic elements) prototypes evidencing speed, energy efficiency and scalability when illuminated with femtosecond laser pulses.

Missions

At the Institut Jean Lamour, the Research Engineer will participate in the TOPTRONIC project and contribute to the study of new materials that should make it possible to develop new types of magnetic memories and more generally new spintronic devices.
