Theoretical Study of Current-Induced Dynamics Of An Antiferromagnetic Skyrmionium

Theoretical Study of Current-Induced Dynamics Of An Antiferromagnetic Skyrmionium ABSTRACT In this thesis, we present a theoretical study on the current-induced nucleation and propagation of antiferromagnetic skyrmionium. A skyrmionium, also known as 2π-skyrmion, is a vortex-like magnetic structure characterized by zero topological charge. We show by means of micro-magnetic simulation that an antiferromagnetic skyrmionium can […]
