Study of Spin Transfer Torque (STT) and Spin Orbit Torque (SOT) Magnetic Tunnel Junctions (MTJS) at Advanced CMOS Technology Nodes

Electrical and Electronics Engineering: An International Journal, 2017
Magnetic Random Access Memory (MRAM) is a promising candidate to be the universal non-volatile (NV) storage device. The Magnetic Tunnel Junction (MTJ) is the cornerstone of the NV-MRAM technology. 2-terminal MTJ based on Spin Transfer Torque (STT) switching is considered as a hot topic for academic and industrial researchers.

Topological spin-orbit torque in ferrimagnetic Weyl semimetal

Physical Review Research
We theoretically find a topological spin-orbit torque (SOT) in the compensated ferrimagnetic Weyl semimetal Ti_{2}MnAl. The topological SOT arises from all the occupied states, which is free from dissipation. However, it is negligible in metallic magnets
