Laser-Induced Demagnetization at Ultrashort Time Scales: Predictions of TDDFT

Laser-Induced Demagnetization at Ultrashort Time Scales: Predictions of TDDFT

Time-dependent density functional theory (TDDFT) is implemented in an all electron solid-state code for the case of fully unconstrained noncollinear spins. We use this to study intense, short, laser pulse-induced demagnetization in bulk Fe, Co, Ni and find that demagnetization can take place on time...
