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 …

Abstract Magneto-optical (MO) effects, viz. magnetically induced changes in light intensity or
polarization upon reflection from or transmission through a magnetic sample, were …

We investigate the spin dynamics driven by terahertz magnetic fields in epitaxial thin films of
cobalt in its three crystalline phases. The terahertz magnetic field generates a torque on the …

We have numerically solved the Landau-Lifshitz-Gilbert (LLG) equation in its standard and
inertial forms to study the magnetization switching dynamics in a 3 d thin film ferromagnet …

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 spin …

Recent experimental observation of inertial spin dynamics calls upon holistic reevaluation of
the theoretical framework of magnetic resonance in ferromagnets. Here, we derive the …

Using valid experimental parameters, we quantify the magnitude of resonantly phonon-
driven precession of exchange magnons in freestanding ferromagnetic nickel thin films on …

Spin-nutation resonance has been well explored in one-sublattice ferromagnets. Here, we
investigate the spin nutation in two-sublattice antiferromagnets as well as, for comparison …

Terahertz (THz) spin waves or their quanta, magnons, can be efficiently excited by acoustic
phonons because these excitations have similar wave vectors in the THz regime. THz …

Magnetization dynamics and spin waves in ferromagnets are investigated using the inertial
Landau-Lifshitz-Gilbert equation. Taking inertial magnetization dynamics into account …
