Partner 2: Institut Jean Lamour - CNRS
Role in the project
CNRS will fabricate and study the GREEN-MEM systems to evaluate the interconversion and torque efficiency, by spin/orbital pumping FMR and spin/orbital torque FMR techniques, second harmonic and current-induced switching. We have up to 4 sputtering equipment to grow and combine different materials; particularly the interfaces to convert orbital current to charge current such as Cu/MgO and Co/Al, among others. The GREEN-MEM-funded hired researcher will be trained in optical lithography and FMR-based measurements, as spin/orbital pumping and electronic lithography for the development of the micro- and nano-devices in WP4.
Team qualification in the field of proposal
The Institut Jean Lamour (IJL) is a joint research unit (UMR 7198) of CNRS and Université de Lorraine. The researchg at IJL is focused on materials and processes science and engineering, covering: materials, metallurgy, plasmas, surfaces, nanomaterials and electronics. It regroups 183 researchers/lecturers, 91 engineers/technicians/administrative staff, 150 doctoral students and 25 post-doctoral fellows. Partnerships exist with 150 companies and the IJL research groups collaborate with more than 30 countries throughout the world. Its exceptional instrumental platforms are spread over 4 sites; the main one is located on Artem campus in Nancy.
The project will be carried out within the SPIN team whose subjects range from the development of innovative materials for implementation in spin electronics devices, to the development of magnetic sensors and the fundamental study of physical phenomena related to magnetism.
The Principal Investigator from IJL is Prof. Juan-Carlos Rojas-Sánchez, a world-renowned expert in the interconversion of spin current to charge current, particularly for the quantification of relevant spintronic parameters such as the interconversion efficiency and the characteristic lengths.
Prof. Sebastien Petit-Watelot is associate professor at the University of Lorraine, who is also an expert in magneto-transport, FMR and spin pumping
Prof. Michel Hehn is a specialist in thin film growth by sputtering.
Laurent Badie and Demba Ba are cleanroom’s engineers responsible for optical and e-beam lithography.
Scientific infrastructure
The IJL has several experimental facilities and platforms. Notably, for the project we will make available our spin and orbital pumping FMR and spin-torque FMR measurements. The measurements can be performed between 10 K and 350 K, with magnetic field up to +/-0.6 T and microwave frequency up to 40 GHz. The clean room platform counts with state-of-the-art equipment for fabrication of micro- and nano-devices. The growth platform, complementary to that of our partners. Also the team has access to a magnetic characterization platform consisting of two VSM SQUID, and 4 PPMS, including an exclusive one to measure FMR, and another one to measure magneto-transport between 2 and 350 K, with fields up to 9 T, and rotation inside and outside the thin film plane. Additionally, a magneto-transport equipment, at room temperature and with a DC magnetic field up to 0.4 T. This equipment is mainly used for spin/orbit Seebeck effect measurements, and some complementary spin-orbit torque measurements.
