What is Rodlike Heisenberg nanomagnet driven by propagating magnetic field: Nonequilibrium phase transition about?

The dynamical responses of a rodlike anisotropic Heisenberg ferromagnet, irradiated by the propagating magnetic field wave, have been studied by Monte Carlo simulation using Metropolis single spin-flip algorithm. A nonequilibrium dynamical phase transition has been observed. The transition temperature has been obtained from the peak position of the variance of the dynamic order parameter plotted as a function of the temperature. The transition has been found to occur at a lower temperature for the higher value of the amplitude of the propagating magnetic field wave. A comprehensive phase boundary was drawn. The phase boundary has been found to be insensitive to the wavelength of the propagating field wave. The boundary encloses more area of the region of the ordered phase for stronger anisotropy.
