To study the temperature dependence of magnetic properties of permanent magnets, methods of treating the thermal fluctuation causing the thermal activation phenomena must be established. To study finite-temperature properties quantitatively, we need

The microscopic mechanism of coercivity at finite temperature is a crucial issue for permanent magnets. Here we present the temperature dependence of the coercivity of an atomistic spin model for the highest-performance magnet Nd2Fe14B. For quantitat

The thermal and dynamical properties Nd2Fe14B at finite temperatures are studied with an atomic model Hamiltonian. The temperature dependence of the magnetization including the reorientation transition was obtained successfully. Moreover, the atom-sp

We examine the anisotropic properties of the exchange stiffness constant $\mathcal{A}$ for a rare-earth permanent magnet, ${\mathrm{Nd}}_{2}{\mathrm{Fe}}_{14}\mathrm{B}$, by connecting analyses with two different scales of length, i.e., Monte Carlo (

We developed an efficient method for Monte Carlo simulations with long-range interacting systems. The present method is based on the stochastic potential switching algorithm as in the case of the stochastic cutoff (SCO) method. Compared with the SCO
