Magnetization switching in small samples caused by the interaction of conducting electrons and electromagnetic radiation

Magnetization reversal of ferromagnetic nanosample by circularly polarized radiation pulse under resonance condition

“…The calculated dynamics of the magnetization demonstrate the possibility of magnetization switching. This is the principal difference with our article [24], where the transitions between the bands of the same spin were considered. In the present work, we consider the transition between bands of opposite spins.…”

“…Here, we consider another method of magnetization reversal in nanosized samples. In our previous article [24], it was clearly shown that the spin-orbit coupling (SOC) of electrons with the electric field of an incident electromagnetic wave is a fairly effective mechanism for the magnetization reversal of nanosized ferromagnetic samples. In particular, the resonance character of the dependence of the induced magnetic moment on the frequency of the radiation is found.…”
