Relativistic theory of spin relaxation mechanisms in the Landau-Lifshitz-Gilbert equation of spin dynamics
Ritwik Mondal, Marco Berritta, Peter M. Oppeneer
Starting from the Dirac-Kohn-Sham equation we derive the relativistic equation of motion of spin angular momentum in a magnetic solid under an external electromagnetic field. This…
Magnetization switching of FePt nanoparticle recording medium by femtosecond laser pulses
R. John, M. Berritta, D. Hinzke +11
Manipulation of magnetization with ultrashort laser pulses is promising for information storage device applications. The dynamic of the magnetization response depends on the energy…
Ab Initio Theory of Coherent Laser-Induced Magnetization in Metals
Marco Berritta, Ritwik Mondal, Karel Carva +1
We present the first materials specific ab initio theory of the magnetization induced by circularly polarized laser light in metals. Our calculations are based on non-linear densit…
