Magnetic response of the spin-1/2 cylindrical nanowire to the propagating
magnetic field wave has been investigated by means of Monte Carlo simulation
method based on Metropolis algorithm. The obtained microscopic spin
configurations suggest that the studied system exhibits two types of dynamical
phases depending on the considered values of system parameters: Coherent
propagation of spin bands and spin-frozen or pinned phases, as in the case of
the conventional bulk systems under the influence of a propagating magnetic
field. By benefiting from the temperature dependencies of variances of dynamic
order parameter, internal energy and the derivative of dynamic order parameter
of the system, dynamic phase diagrams are also obtained in related planes for
varying values of the wavelength of the propagating magnetic field. Our
simulation results demonstrate that as the strength of the field amplitude is
increased, the phase transition points tend to shift to the relatively lower
temperature regions. Moreover, it has been observed that dynamic phase boundary
line shrinks inward when the value of wavelength of the external field
decreases.Comment: 7 pages, 4 figure
