Nutation in antiferromagnetic resonance
Ritwik Mondal, Sebastian Großenbach, Levente Rózsa +1
The effect of inertial spin dynamics is compared between ferromagnetic, antiferromagnetic and ferrimagnetic systems. The linear response to an oscillating external magnetic field i…
Terahertz spin dynamics driven by an optical spin-orbit torque
Ritwik Mondal, Andreas Donges, Ulrich Nowak
Spin torques are at the heart of spin manipulations in spintronic devices. Here, we examine the existence of an optical spin-orbit torque, a relativistic spin torque originating fr…
Dynamics of the relativistic electron spin in an electromagnetic field
Ritwik Mondal, Peter M. Oppeneer
A relativistic spin operator cannot be uniquely defined within relativistic quantum mechanics. Previously, different proper relativistic spin operators have been proposed, such as…
