Superdiffusive Spin Transport as a Mechanism of Ultrafast Demagnetization

Original language description

We propose a semiclassical model for femtosecond laser-induced demagnetization due to spinpolarized excited electron diffusion in the superdiffusive regime. Solving the derived transport equation numerically we show that this mechanism accounts for the experimentally observed demagnetization within 200 fs in Ni, without the need to invoke any angular momentum dissipation channel.
