Scaling of Coercivity in a 3d Random Anisotropy Model
Thomas C. Proctor, Eugene M. Chudnovsky, Dmitry A. Garanin
The random-anisotropy Heisenberg model is numerically studied on lattices containing over ten million spins. The study is focused on hysteresis and metastability due to topological…
Random Fields, Topology, and The Imry-Ma Argument
Thomas C. Proctor, Dmitry A. Garanin, Eugene M. Chudnovsky
We consider -component fixed-length order parameter interacting with a weak random field in dimensions. Relaxation from the initially ordered state and spin-spin corre…
Random Field XY Model in Three Dimensions: The Role of Vortices
D. A. Garanin, E. M. Chudnovsky, T. Proctor
We study vortex states in a 3d random-field XY model of up to one billion lattice spins. Starting with random spin orientations, the sample freezes into the vortex-glass state with…
