## Description

- description: 'We review atomistic spin model studies, a new approach for theoretical
    investigations, on magnetic properties of permanent magnets. In the atomistic
    modeling, the microscopic details of magnetic parameters and lattice structures
    are realistically considered, and the temperature effect, including thermal fluctuation,
    is properly treated based on statistical physics methods: Monte Carlo methods
    and stochastic Landau-Lifshitz-Gilbert equation methods. We introduce how to treat
    thermal effects for static and dynamical properties using these methods. Focusing
    especially on neodymium permanent magnets, we discuss features of magnetization,
    domain wall, coercivity of a grain, nucleation and pinning fields, and dysprosium
    substitution effect, which were first elucidated with those methods.'
