Kinetic Ising model in an oscillating field: Finite-size scaling at the dynamic phase transition
S. W. Sides, P. A. Rikvold, M. A. Novotny
Abstract
We study hysteresis for a two-dimensional, spin-1/2, nearest-neighbor, kinetic Ising ferromagnet in an oscillating field, using Monte Carlo simulations. The period-averaged magnetization is the order parameter for a proposed dynamic phase transition (DPT). To quantify the nature of this transition, we present the first finite-size scaling study of the DPT for this model. Evidence of a diverging correlation length is given, and we provide estimates of the transition frequency and the critical indices β, γ and ν.
