Phase diagram of the dipolar Ising ferromagnet on a kagome lattice
Hisato Komatsu, Yoshihiko Nonomura, Masamichi Nishino
We study the field--temperature phase diagram of the two-dimensional dipolar Ising ferromagnet on a kagome lattice with a specific ratio between the exchange and dipolar constants,…
Phase diagram of the two-dimensional dipolar Heisenberg model with the Dzyaloshinskii-Moriya interaction and the Ising anisotropy
Hisato Komatsu, Yoshihiko Nonomura, Masamichi Nishino
We study phase transitions in the two-dimensional Heisenberg model with the Dzyaloshinskii-Moriya interaction, the Ising anisotropy (), and the dipolar interaction under zero an…
Nontrivial temperature dependence of ferromagnetic resonance frequency for spin reorientation transitions
Masamichi Nishino, Seiji Miyashita
We find unusual temperature dependence of the ferromagnetic resonance (FMR) frequency for the spin-reorientation (SR) transition, in which the easy axis changes dependi…
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-temperature phase diagram for the two-dimensional dipolar Heisenberg model with and without magnetic field
Hisato Komatsu, Yoshihiko Nonomura, Masamichi Nishino
We investigate phase transitions in the two-dimensional dipolar Heisenberg model with uniaxial anisotropy with a specific ratio between the exchange and dipolar constants, . W…
Multistability in an unusual phase diagram induced by the competition between antiferromagnetic-like short-range and ferromagnetic-like long-range interactions
Masamichi Nishino, Per Arne Rikvold, Conor Omand +1
The interplay between competing short-range (SR) and long-range (LR) interactions can cause nontrivial structures in phase diagrams. Recently, horn-shaped unusual structures were f…
