Role of initial magnetic disorder: A time-dependent ab initio study of ultrafast demagnetization mechanisms
Despite more than 20 years of development, the underlying physics of the laser-induced demagnetization process is still debated. We present a fast, real-time time-dependent density functional theory (rt-TDDFT) algorithm together with the phenomenological atomic Landau-Lifshitz-Gilbert model to inves...
