Nonequilibrium phase transitions in model ferromagnets: a review

M Acharyya - International Journal of Modern Physics C, 2005 - World Scientific
The thermodynamical behaviors of ferromagnetic systems in equilibrium are well studied.
However, the ferromagnetic systems far from equilibrium became an interesting field of …

Scaling and dynamics of low-frequency hysteresis loops in ultrathin Co films on a Cu (001) surface

Q Jiang, HN Yang, GC Wang - Physical Review B, 1995 - APS
The hysteresis loops of epitaxially grown ultrathin Co films on a Cu (001) surface with
magnetic anisotropy were measured in situ at room temperature under a periodic external …

Response of Ising systems to oscillating and pulsed fields: Hysteresis, ac, and pulse susceptibility

M Acharyya, BK Chakrabarti - Physical Review B, 1995 - APS
We have studied, using Monte Carlo (MC) simulation for ferromagnetic Ising systems in one
to four dimensions and solving numerically the mean-field (MF) equation of motion, the …

Kinetic Ising model in an oscillating field: Avrami theory for the hysteretic response and finite-size scaling for the dynamic phase transition

SW Sides, PA Rikvold, MA Novotny - Physical Review E, 1999 - APS
Hysteresis is studied for a two-dimensional, spin-1 2, nearest-neighbor, kinetic Ising
ferromagnet in a sinusoidally oscillating field, using Monte Carlo simulations and analytical …

Absence of first-order transition and tricritical point in the dynamic phase diagram of a spatially extended bistable system in an oscillating field

G Korniss, PA Rikvold, MA Novotny - Physical Review E, 2002 - APS
It has been well established that spatially extended, bistable systems that are driven by an
oscillating field exhibit a nonequilibrium dynamic phase transition (DPT). The DPT occurs …

Kinetics of a mixed Ising ferrimagnetic system

GM Buendía, E Machado - Physical Review E, 1998 - APS
We present a study, within a mean-field approach, of the kinetics of a classical mixed Ising
ferrimagnetic model on a square lattice, in which the two interpenetrating square sublattices …

Nonequilibrium phase transition in the kinetic Ising model: Is the transition point the maximum lossy point?

M Acharyya - Physical Review E, 1998 - APS
The nonequilibrium dynamic phase transition, in the kinetic Ising model in presence of an
oscillating magnetic field, has been studied both by Monte Carlo simulation (in two …

Dynamic phase transition in a time-dependent Ginzburg-Landau model in an oscillating field

H Fujisaka, H Tutu, PA Rikvold - Physical Review E, 2001 - APS
Abstract The Ginzburg-Landau model below its critical temperature in a temporally
oscillating external field is studied both theoretically and numerically. As the frequency or the …

Stochastic hysteresis and resonance in a kinetic Ising system

SW Sides, PA Rikvold, MA Novotny - Physical Review E, 1998 - APS
We study hysteresis for a two-dimensional, spin-1/2, nearest-neighbor, kinetic Ising
ferromagnet in an oscillating field, using Monte Carlo simulations and analytical theory …
