Mangetic phase transition for three-dimensional Heisenberg weak random anisotropy model: Monte Carlo study
Ha M. Nguyen, Pai-Yi Hsiao
Magnetic phase transition (MPT) to magnetic quasi-long-range order (QLRO) phase in a three-dimensional Heisenberg weak (D/J=4) random anisotropy (RA) model is investigated by Monte…

Exchange-driven Collective Behavior in a 3D Array of Nanoparticles
Ha M. Nguyen, Pai-Yi Hsiao
A Monte Carlo simulation is performed in a cubic lattice of interacting identical Stoner-Woldfarth nanoparticles. The model system is a randomly-anisotropic Heisenberg spin system…
