[HTML][HTML] Inertial effects in ultrafast spin dynamics

R Mondal, L Rózsa, M Farle, PM Oppeneer… - Journal of Magnetism …, 2023 - Elsevier
The dynamics of magnetic moments consists of a precession around the magnetic field
direction and a relaxation towards the field to minimize the energy. While the magnetic …

Theory of tensorial magnetic inertia in terahertz spin dynamics

S Ghosh, M Cherkasskii, I Barsukov, R Mondal - Physical Review B, 2024 - APS
Magnetic inertia has emerged as a possible way to manipulate ferromagnetic spins at a
higher frequency, eg, terahertz. Theoretical treatments so far have considered the magnetic …
