Hysteresis loop area of the Ising model

The hysteresis of the Ising model in a spatially homogeneous AC field is\nstudied using both mean-field calculations and two-dimensional Monte Carlo\nsimulations. The frequency dispersion and the temperature dependence of the\nhysteresis loop area are studied in relation to the dynamic symmetry loss. The\ndynamic mechanisms may be different when the hysteresis loops are symmetric or\nasymmetric, and they can lead to a double-peak frequency dispersion and\nqualitatively different temperature dependence.\n
