Polyhexatic and Polycrystalline States of Skyrmion Lattices
Dmitry A. Garanin, Eugene M. Chudnovsky
Abstract We report Monte Carlo studies of lattices of up to skyrmions treated as particles with negative core energy and repulsive interaction obtained from a microscopic…
Uniform and non-uniform thermal switching of magnetic particles
D. A. Garanin
The pulse-noise approach to systems of classical spins weakly interacting with the bath has been applied to study thermally-activated escape of magnetic nanoparticles over the unif…
Dipolar ordering and domains in crystals of Mn Ac molecular magnets
D. A. Garanin
Dipolar coupling in crystals of the MnAc molecular magnet elongated along the anisotropy axis favors ferromagnetic ordering below the mean-field Curie temperature 0.71 K. Wi…
Pulse-noise approach for classical spin systems
D. A. Garanin
For systems of classical spins interacting with the bath via damping and thermal noise, the approach is suggested to replace the white noise by a pulse noise acting at regular time…
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…
Ordered vs Disordered States of the Random-Field Model in Three Dimensions
D. A. Garanin, E. M. Chudnovsky
We report numerical investigation of the glassy behavior of random-field exchange models in three dimensions. Correlation of energy with the magnetization for different numbers of…
