test.jpgSpintronics and spinorbitronics

Spinorbitronics concerns the use of spin-orbit coupling (SOC) in nonmagnetic materials to generate, detect or exploit spin-polarized currents. This opens the way to control spintronic devices without the use of magnetic fields through the current induced spin-orbit torques (SOTs). Moreover, SOC in magnetic multilayer stacks lacking inversion symmetry promotes, via the interfacial Dzyalosinskii-Moriya interaction (IDMI), chiral spin textures, like skyrminons, that can be efficiently driven SOTs.

   

The spinorbitronics research direction of C4S is coordinated by M. Gabor.  Our most important results are obtained within the projects:

- PN-III-P4-ID-PCE-2020-1853 No. 182/04/01/2021 - Spin-orbit torque driven field-free artificial synapses and neurons 

- PN-III-P1-1.1-TE-2016-2131 No. 24/02.05.2018 - Spin-orbitronic devices for non-volatile magnetic memory elements 

- PNII-RU-TE nr.255/01.10.2015PNII-RU-TE nr.255/01.10.2015 --Advanced spintronic devices for communication and data storage technologies based on Heusler compounds
