The magnetic wall structures of the one dimensional (1D) anisotropic XY-spin system under an oscillating magnetic field were studied using the Ginzburg-Landau model. It was numerically shown that there exist two types of walls, the Néel and Bloch walls. The phase diagram for the stable wall structures spanned by the amplitude and the frequency of the external field. It was shown that the Néel-Bloch transition can be either continuous or discontinuous depending on the value of the frequency of the applied magnetic field.
