Nanofabrication of Magnetic Tunnel Junctions for Sustainable Spintronics (M/F)

Job Description

Missions

The successful candidate will:
1. Optimize the nanopatterning process in cleanroom by e-beam lithography to achieve the desired nanodevices geomertry.
2. Adapt a setup to enable sub-nanosecond pulse measurements (down to 100 ps).
3. Test different materials (provided by IJL's growth facilities or partners) for the optimization of the control of the magnetization of the free layer of the MTJ. The tested systems will include graphene-intercalated systems.

Activity

This position is part of the M-ERA.NET "GREEN MEM" project (ANR-25-MER3-0007-01), which aims to develop sustainable, non-polluting materials for advanced spintronics devices to address the unsustainable energy consumption of AI and big-data computing. The consortium includes partners in France (IJL), in Spain (IMDEA, U. Autonoma de Madrid) and Poland (SOLARIS)

The IJL team's role in the project is to develop complete nanodevices for spintronics applications, including current-induced spin-orbit torques (SOT) in magnetic tunnel junctions (MTJs) made from novel, sustainable materials

Your Profil

Skills

The candidate must have a strong background in spin-electronics and clean room processes including especially e-beam lithography. She/He should have a base knowledge of spin-orbit torque, spin-transfer torque, spin-charge current interconversion and the underlaying characterisation technics. The candidate should also have some experience in micromagnetic simulations (desirable), and good knowledge of LabVIEW or Python is a plus.
