| dc.description | Taking into account the magnetostatic interactions is equivalent to introducing a new term in the anisotropy field as long as only spin waves perpendicular to the wall are studied. Within this restriction, the authors studied the localised magnons in a Bloch wall, both in the sharp boundary limit when K/J><sup>4</sup>/<sub>3</sub>, and in the regime where the wall is a few atomic distances wide. They showed that the mode arising from the translation mode of the continuum limit varies continuously as a function of anisotropy over the whole range. The other mode below the bulk spin waves plays the role of a soft mode at the transition K/J=<sup>4</sup>/<sub>3</sub>, between a Bloch wall and a sharp boundary between domains. The polarisations of both modes are discussed. |
