Gabay-Toulouse Phase Transition in Heisenberg Spin-Glasses in Three Dimensions
T. Shirakura, D. Ninomiya, Y. Iyama +1
We examine three-dimensional Heisenberg models with and without random anisotropies in a magnetic field. We calculate both the stiffness exponent at absolute zero tem…

Phase Transition of a Heisenberg Spin-Glass Model in Three Dimensions
F. Matsubara, T. Shirakura, S. Endoh
We study the phase transition of the Heisenberg model in three dimensions. Using a dynamical simulation method that removes a drift of the system, the existence of the spin…

Circular phase of a two dimensional ferromagnet with dipolar interactions
Fumitaka Matsubara, Junya Sasaki
We make for the first time a large-scale Monte-Carlo simulation of a ferromagnetic Heisenberg model with dipolar interactions on a two dimensional square lattice with open boundari…
