Quasi-Equilibrium Stoner-Wohlfarth Versus Strongly Out-of-Equilibrium Dynamics in HAMR

The heat-assisted magnetic recording (HAMR) technology is one of the most promising alternatives to replace conventional perpendicular magnetic recording (PMR). To better understand the writing processes involved in HAMR, a better description of the magnetization dynamics at elevated temperatures is...
