  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.
