We investigate static and dynamical properties of the Nd permanent magnet, Nd2Fe14B, using a recently developed atomistic model. We show the temperature dependence of magnetizations and domain wall profiles by a Monte Carlo method. With the use of the stochastic Landau-Lifshitz-Gilbert method, we present an unusual temperature dependence of the ferromagnetic resonance frequency. By introducing a statistical method which extends the limitation of the simulation time, we estimate the coercive force of a single grain. We also show the surface anisotropy effect of Nd atoms on the coercive force and nucleation and pinning fields in a prototype hard-soft-hard magnet model. |
