Superdiffusive electron transport mediates laser-induced demagnetization
Description:
The mechanics of laser-induced demagnetization has attracted considerable attention in efforts to develop fast-switching optomagnetic logic devices. A femtosecond laser pulse for instance can demagnetize a ferromagnet within a few hundred femtoseconds. Various theories have been proposed to explain how an ultrafast laser pulse can demagnetize a magnetic thin film, ranging from indirect spin-flip scattering to direct laser-induced spin flips.
