Bridging together material science, ferroelectricity and spin electronics in antiferromagnetic perovskite oxides, CITRON will explore new routes for tailoring multifunctional properties – by design – in vanadate-based systems, especially for the spin manipulation operated by an electric fields.

Summary: Bridging together material science, ferroelectricity and spin electronics in antiferromagnetic perovskite oxides, CITRON will explore new routes for tailoring multifunctional properties – by design – in vanadate-based systems, especially for the spin manipulation operated by an electric fields.
The project will be organized towards 4 main objectives: (i) grow and design epitaxial RVO3 thin films and superlattices in order to tailor the electron degrees of freedom (spin, orbital charge) the lattice distortions and atomic arrangements. (ii) characterize – in depth – the crystalline structure and interactions using advanced characterization tools and determine the intimate couplings and interactions at the microscopic scale. (iii) Unravel the ferroelectric character of designed R’VO3/RVO3 superlattices and its relation to the crystalline structure through epitaxial/chemical strain engineering. (iv) assemble the charge order and spin order building blocks for the electric control of magnetic states in RVO3-systems and spin transport phenomena.
