Spin-orbit torque manipulation of sub-terahertz magnons in antiferromagnetic α-Fe2O3

Posted by in category: particle physics

Antiferromagnetic spintronics offer high speed operations, and reduced issues with stray fields compared to ferromagnetic systems, however, antiferromagnets are typically more challenging to manipulate electrically. Here, Yang, Kim, and coauthors demonstrate electrical control of magnon dispersion and frequency in an α-Fe2O3/Pt heterostructure.
