Open positions

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.

Offer: Two year post-doc position starting between September 2021 and March of 2022.

Project description:

This ANR funded project will focus on the experimental generation and characterization of spin-orbit torques at the picosecond timescale. The project will be a continuation of our recent work published in Nature Electronics, which can be seen by clicking here.

The postdoc will be in charge of sample preparation (mostly lithography steps in clean-room), characterization (VSM, MOKE, transport measurements…) and performing ultrafast pump-probe experiments with both optical and picosecond electrical pulses.

We are looking for an excellent candidate with experience in any/many of the following themes: spintronics, spin-orbitronics, ultrafast optics/magnetism, RF electronics,THz spintronics…

Application:  Send a letter of motivation, a full CV and contact information for 2 professional references to the contact email.

Offer :    One year post-doc/enginner position starting in autumn 2020 (contract can be extended after one year)  


Context:   The Institut Jean Lamour (IJL) at Université de Lorraine is one of the largest material sciences institute in Europe with about 550 people. It hosts a magnetometry plateform based on 9 magnetometers (2 SQUID-VSM, 3 PPMSs, 3 VSMs, 1 MOKE) and relying on two staff members. Our plateform carries actions mostly in physics, chemistry and nanosciences, but also in metallurgy, geology and sciences for living systems. It welcomes academic users as well as engineers from private companies. The R&D catalogue covers a large spectrum of services proposed to any European SMEs and industries : magnetometry measurement service, R&D collaboration, training or advicing, metrology development.


Institut Jean Lamour is one of the leading partners of the French and European Magnetometry Network ( and Both networks aim to build community in the field of magnetometry in order to : intensify scientific and technical exchanges between magnetometry users ; chair, maintain and improve knowledge, know-how and good practices ; favour the accessibility of magnetometry platforms to academic and R&D researcher ; teach and train young scientists and engineers in the field of magnetometry.

Objectives:  There are two main objectives for the post-doc/engineer work. The first task is internal to IJL plateform. The post-doc/engineer must optimize the magnetometry tools, train new regular users, perform measurement service for non-regular academic and private users, and participate to on-going scientific projects. The post-doc/engineer will also participate to R&D projects of the plateform. The second role consists in developing and promoting the networks R&D activities. This includes website improvement, lifelong training, meeting new partners, performing R&D work.

Location : Post-doc work will be located at Institut Jean Lamour at Nancy (France)


Candidates :  PhD in physics, materials science, chemistry, engineering. The candidate should have a strong expertise in magnetic measurement. The candidate must enjoy experimental and team work. Experience with French language and with WordPress software are welcome.


Application :  Please send a letter of motivation, CV, diplomas references details to the contact e-mails.

Title of the job offer Topological Spintronics



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. In addition, their particular characteristics could also be used to propose new spin-caloritronic devices to exploit energy losses due to joule heating of adjacent components.

The objective of the TOPTRONIC project ( is to characterize topological insulators, mainly alpha-phase tin, coupled with Heusler alloys for their spintronics and spin-caloritronics exploitation. We currently have a wide range of experimental setups including dc and microwave electrical characterization devices for the study of the conversion of charge current to spin current and vice versa, and to explore the possibility of switching the magnetization of a magnetic material thanks to new phenomena based on spin-orbit coupling.


The main tasks will be electrical and magnetotransport characterization including clean room activity to perform optical or e-beam lithography.

The Research Engineer will set up new experiments for which knowledge of LabVIEW is required as well as experience in magnetotransport measurements using dc, ac, pulsed currents or voltages and lock-in detection. She/he will propose and set new experiments.


We are seeking a highly motivated fellow with the following skills:

Theoretical knowledge: strong background in solid-state physics.

Experimental: mastery of tools and techniques in clean rooms (optical/electronic lithography) and experience in electrical characterization of thin films or devices based on heavy metals, semiconductors, magnetic materials or topological insulators.

Constraints and risks

No major risk.
