Theory of tensorial magnetic inertia in terahertz spin dynamics
Subhadip Ghosh, Mikhail Cherkasskii, Igor Barsukov +1
Magnetic inertia has emerged as a possible way to manipulate ferromagnetic spins at a higher frequency e.g., THz. Theoretical treatments so far have considered the magnetic inertia…
Inertial spin waves in spin spirals
Mikhail Cherkasskii, Ritwik Mondal, Levente Rózsa
Inertial effects in spin dynamics emerge on picosecond time scales, giving rise to nutational excitations at THz frequencies. Here, we describe a general framework for investigatin…
Inertial spin waves in ferromagnets and antiferromagnets
Ritwik Mondal, Levente Rózsa
Inertial effects in spin dynamics are theoretically predicted to emerge at ultrashort time scales, but their experimental signatures are often ambiguous. Here, we calculate the spi…
Theory of inertial spin dynamics in anisotropic ferromagnets
Mikhail Cherkasskii, Igor Barsukov, Ritwik Mondal +2
Recent experimental observation of inertial spin dynamics calls upon holistic reevaluation of the theoretical framework of magnetic resonance in ferromagnets. Here, we derive the s…
Spin pumping at terahertz nutation resonances
Ritwik Mondal, Akashdeep Kamra
We investigate spin pumping current injected by the nutation resonances of a ferromagnet or an antiferromagnet into an adjacent metal. Comparing the dc spin pumping current between…
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…
