Micromagnetic simulation of spin torque ferromagnetic resonance in nano-ring-shape confined magnetic tunnel junctions
TL;DR: In this article, the authors employed micromagnetic simulation to study the spin-torque excited ferromagnetic resonance (ST-FMR) property in a nano-ring shaped magnetic tunnel junction, revealing that two resonance states with different resonance frequencies are excited by a microwave frequency current or magnetic field.
