Magnetic Properties of 2-Dimensional Dipolar Squares: Boundary Geometry Dependence
Ryoko Sugano, Katsuyoshi Matsushita, Akiyoshi Kuroda +2
By means of the molecular dynamics simulation on gradual cooling processes, we investigate magnetic properties of classical spin systems only with the magnetic dipole-dipole intera…
Computational Experiment on Glassy Dynamic Nature of the Field-Cooled Magnetization in an Ising Spin-Glass Model
Hajime Takayama, Koji Hukushima
The field-cooled (FC) process on an Ising spin-glass model is investigated by a standard Monte Calro (MC) method on one hand, and the equilibrium magnetization of the same system i…
Finite dipolar hexagonal columns on piled layers of triangular lattice
Katsuyoshi Matsushita, Ryoko Sugano, Akiyoshi Kuroda +2
We have investigated, by the Monte Carlo simulation, spin systems which represent moments of arrayed magnetic nanoparticles interacting with each other only by the dipole-dipole in…
Spin melting and refreezing driven by uniaxial compression on a dipolar hexagonal plate
Katsuyoshi Matsushita, Ryoko Sugano, Akiyoshi Kuroda +2
We investigate freezing characteristics of a finite dipolar hexagonal plate by the Monte Carlo simulation. The hexagonal plate is cut out from a piled triangular lattice of three l…
Bond-Dilution-Induced Quantum Phase Transitions in Heisenberg Antiferromagnets
Chitoshi Yasuda, Synge Todo, Hajime Takayama
Bond-dilution effects on the ground state of the square-lattice antiferromagnetic Heisenberg model, consisting of coupled bond-alternating chains, are investigated by means of the…
An Extended Scaling Scheme for Critically Divergent Quantities in Ferromagnets and Spin Glasses
I. A. Campbell, K. Hukushima, H. Takayama
From a consideration of high temperature series expansions in ferromagnets and in spin glasses, we propose an extended scaling scaling scheme involving a set of scaling formulae wh…
