Thermal behavior of superparamagnetic cobalt nanodots explored by anisotropic magnetic molecular dynamics simulations

A comparison between atomistic spin dynamics and magnetic molecular dynamics is performed to discuss the influence of various forms of the magnetic anisotropy energy, to reproduce the thermal behavior of superparamagnetic cobalt nanodots. Both classical spins and lattice vibrations are, for the firs...

Zusammenfassung:A comparison between atomistic spin dynamics and magnetic molecular dynamics is performed to discuss the influence of various forms of the magnetic anisotropy energy, to reproduce the thermal behavior of superparamagnetic cobalt nanodots. Both classical spins and lattice vibrations are, for the first time, treated simultaneously to explore magnetic thermal effects.
