モンテカルロ法による強磁性ヒステリシスの平衡・非平衡シミュレーション

2008 年 38 巻 p. 9-15

Equilibrium and non-equilibrium hysteresis of 3D Ising and Heisenberg model are studied using the Monte Carlo method at various temperatures. Hysteresis loops of equilibrium simulation show qualitative agreement with those of　the static mean-field theory. In non-equilibrium simulation, squareness of the hysteresis loops is lower than that in equilibrium simulation, and the coercivities have non-zero values in the temperatures above the equilibrium Curie point.
