Phase diagram of multi-layer ferromagnet system with dipole-dipole interaction
Taichi Hinokihara, Seiji Miyashita
We investigate various magnetic configurations caused by the dipole-dipole interaction (DDI) in the thin-film magnet with the perpendicular anisotropy under the open boundary condi…
The effect of the surface magnetic anisotropy of the neodymium atoms on the coercivity in the neodymium permanent magnet
Masamichi Nishino, Ismail Enes Uysal, Seiji Miyashita
The Nd permanent magnet (NdFeB) is an indispensable material used in modern energy conversion devices. The realization of high coercivity at finite temperatures is a b…
Anisotropy of exchange stiffness based on atomic-scale magnetic properties in rare-earth permanent magnet NdFeB
Yuta Toga, Masamichi Nishino, Seiji Miyashita +2
We examine the anisotropic properties of the exchange stiffness constant, , for rare-earth permanent magnet, NdFeB, by connecting analyses with two differen…
Monte Carlo analysis for finite temperature magnetism of NdFeB permanent magnet
Yuta Toga, Munehisa Matsumoto, Seiji Miyashita +4
We investigate the effects of magnetic inhomogeneities and thermal fluctuations on the magnetic properties of a rare earth intermetallic compound, NdFeB. The constrained…
Temperature dependence of the threshold magnetic field for nucleation and domain wall propagation in an inhomogeneous structure with grain boundary
Sasmita Mohakud, Sergio Andraus, Masamichi Nishino +2
In order to study the dependence of the coercive force of sintered magnets on temperature, nucleation and domain wall propagation at the grain boundary are studied as rate-determin…
Realization of the thermal equilibrium in inhomogeneous magnetic systems by the Landau-Lifshitz-Gilbert equation with stochastic noise, and its dynamical aspects
Masamichi Nishino, Seiji Miyashita
It is crucially important to investigate effects of temperature on magnetic properties such as critical phenomena, nucleation, pinning, domain wall motion, coercivity, etc. The Lan…
