Abstract

The spin dynamics of nanodots in the thermally induced linear reversal mode have been studied by atomistic simulation. A systematic investigation was conducted of the dependence of the properties of heat-assisted magnetization reversal on the thermal pulse width and the elevated peak temperature. An order-of-magnitude decrease in the reversal field was demonstrated for a sub-nanosecond thermal-pulse width and a peak temperature just above the Curie point. The required reversal field was found to increase with atomic uniaxial anisotropy even in the non-equilibrium field cooling process.
