The FEOrgSpin ANR project focuses on properties of hybrid ferromagnetic metal/Ferroelectric organic interfaces which can exhibit high efficient spin-filtering. Recent achievement demonstrates that the spin-polarization at poly(vinylidene fluoride) (PVDF)/Co spinterface can be actively modulated (and even change sign) by switching the ferroelectric (FE) polarization of PVDF [Adv. Mater. 28, 10204 (2016)]. In this project, we aim to expand our knowledge on ferroelectric control of spin polarization at different FE-organic/ferromagnetic spinterface, and develop novel functionalities of spintronic device based on ferroelectric organics. The partners of the project are: Institut Jean Lamour (Nancy, France), Unité de Catalyse et Chimie du Solide (Lens, France) and SPINTEC (Grenoble, France).
The task of the postdoctoral student is the design, synthesis and optimization of the PVDF/ferromagnetic junctions on semiconducting and two-dimensional (graphene) materials. The possibility to integrate the FE-organic/ferromagnetic junctions on flexible substrates will also be explored. The postdoctoral student will use various experimental technics available in lab or in large instrument facilities such as synchrotron source in order to characterize and study the structures. He will have in charge the analysis of the physical properties of organic-based devices by photoemission, multiscale transport techniques and Hanle type spin accumulation measurements.
The successful candidate will have a good knowledge in solid state physics and an experience in the field of spintronics. Experience on the organic layer or 2D materials will be appreciated. Ability to work independently and in a collaborative environment is needed.
The Institut de Physique de Rennes (IPR UMR 6251), organized in six research departments, is a joint research unit of the CNRS and the Université of Rennes 1. The candidate will join the Materials and Nanosciences department. The activities of the department aim at enhancing the fundamental knowledge of condensed matter at the nanometer scale, and providing supports for the development of new materials or devices for spintronics, photonics or information storage. Our group has a long-standing experience in interface-surface physics and spintronics.
It offers a very stimulating scientific environment with many facilities such as the photoemission or near field microscopy setups.
