Relaxation process of magnetic friction under sudden changes in velocity
Hisato Komatsu
Although there have been many studies of statistical mechanical models of magnetic friction, most of these have focused on the behavior in the steady state. In this study, we prepa…
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…
A model of magnetic friction obeying the Dieterich--Ruina law in the steady state
Hisato Komatsu
We propose a model of magnetic friction and investigate the relation between the frictional force and the relative velocity of surfaces in the steady state. The model comprises two…
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…
Temperature-field phase diagram of the two-dimensional dipolar Ising ferromagnet
Hisato Komatsu, Yoshihiko Nonomura, Masamichi Nishino
We study field-induced phase transitions in the two-dimensional dipolar Ising ferromagnet with a specific ratio between the exchange and dipolar constants, , which exhibits a…
A "mean-field approximation" on the phase transitions of three-dimensional Lennard-Jones model
Hisato Komatsu
It is difficult to derive the solid-fluid transition theoretically from microscopic models, although this phenomenon itself has been investigated for a long time. We previously con…
