Missions

The goal of the project is to study the magnetic properties and spin-orbitronics phenomena in van der Waals 2D magnets. The project will focus on single- or few-monolayer thick (Fe,Co)NGeTe2 (N=3-5) alloys grown by molecular beam epitaxy and possibly interfaced with other 2D materials. These 2D magnets are particularly interesting for their high Curie temperature and for the high tunability of magnetic properties when varying the chemical composition. The candidate will investigate spin-orbit torques and electrostatic control of magnetism. The work will primarily consist in magnetotransport experiments (including the patterning of devices). The researcher will also be associated to the growth of multilayers by molecular beam epitaxy and to relevant magnetic measurements (Kerr, SQUID, XMCD).

Activités

- Device patterning by optical lithography in clean room
- Magnetotransport/magneto-optical measurements (Hall, MOKE, MCD)
- Data analysis, article preparation and participation to conferences
- Possibly, fabrication of van der Waals thin films and multilayers by molecular beam epitaxy
- Contribution to material and interface characterization (magnetic, structural, electronic), in house and possibly at synchrotron (XMCD)

Compétences

The candidate must hold a PhD in physics, with a good knowledge of magnetism, spintronics and/or physics of 2D materials. A previous experience with nanofabrication and magnetotransport will be highly valued. The candidate is expected to show good skills for team working, as well as a good autonomy. Self-motivation and a high level track record of publications will be positively considered.

Contexte de travail

SPINTEC (SPINtronics and TEchnology of Components) is a joint research unit of CNRS, CEA, and University of Grenoble Alpes, and one of the leading spintronics research laboratories worldwide. Ideally located on the MINATEC campus in Grenoble, SPINTEC gathers physicists and engineers from the academic and the industrial world. The laboratory currently gathers 100 persons of which 42 permanent staff and about 40 PhD students, postdocs and international visitors. The project will be done in the « 2D and Semiconductor Spintronics » team (http://www.spintec.fr/research/2d-spintronics/). The available equipment spans the growth of layered materials (several MBEs), their characterization (RHEED, XPS, XRD, SQUID, MOKE, Raman, AFM, HR-TEM…), their patterning (optical/e-beam lithography) and the study of spin properties (7T cryostat, magneto-optical setups…) The team already masters the growth of 2D ferromagnets (see refs.). The position is funded by the French National Research Agency (ANR JCJC ELMAX project). Its duration is 12 months with possible extension.
