Description We have performed a numerical simulation of magnetization switching and oscillations in a ferromagnetic
single-domain particle in the disk form under the influence of nanosecond laser pulses with linear
and circular polarization. The analysis has shown that the interaction of laser pulses with a ferromagnetic
nanodisk leads to change in the direction of its magnetization. This process is accompanied by magnetization
oscillations with duration from units to tens of nanoseconds. As it follows from the obtained results,
the main cause of magnetization switching is the reduction of magnetic anisotropy energy at heating of the
structure by laser. The field of the inverse Faraday effect can lead to an increase in frequency and amplitude
of this oscillations.
