Title:
シミュレーション方法、シミュレーション装置、及びプログラム
Document Type and Number:
Japanese Patent JP7462581
Kind Code:
B2
Abstract:
A simulation method includes coarse-graining a plurality of atoms that constitute a magnetic body to be simulated and generating a magnetic body model composed of a collection of particles, applying a magnetic moment to each of a plurality of the particles of the magnetic body model, obtaining a magnetic field due to an interparticle exchange interaction acting between the plurality of particles, based on an interatomic exchange interaction of the magnetic body, obtaining an oscillating magnetic field acting on each of the plurality of particles, based on an oscillating magnetic field originating from a thermal fluctuation acting on the atoms, obtaining a total magnetic field acting on each of the plurality of particles, based on the magnetic field and the oscillating magnetic field, and time-evolving the magnetic moment of each of the plurality of particles, based on the total magnetic field acting on each of the plurality of particles.
