Theory of magnetic inertial dynamics in two-sublattice ferromagnets
Ritwik Mondal
The magnetic inertial dynamics have been investigated for one sublattice ferromagnets. Here, we develop the magnetization dynamics in two-sublattice ferromagnets including the intr…
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…
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…
Terahertz spin dynamics driven by a field-derivative torque
Ritwik Mondal, Andreas Donges, Ulrike Ritzmann +2
Efficient manipulation of magnetization at ultrashort time scales is of particular interest for future technology. Here, we numerically investigate the influence of the so-called f…
Unified theory of magnetization dynamics with relativistic and nonrelativistic spin torques
Ritwik Mondal, Marco Berritta, Peter M. Oppeneer
Spin torques play a crucial role in operative properties of modern spintronic devices. To study current-driven magnetization dynamics, spin-torque terms providing the action of spi…
Generalisation of Gilbert damping and magnetic inertia parameter as a series of higher-order relativistic terms
Ritwik Mondal, Marco Berritta, Peter M. Oppeneer
The phenomenological Landau-Lifshitz-Gilbert (LLG) equation of motion remains as the cornerstone of contemporary magnetisation dynamics studies, wherein the Gilbert damping paramet…
