Abstract: | It is well known that in the uniaxial ferromagnet in the presence of an external magnetic field perpendicular to the easy axis (hx) a continuous phase transition occurs for a critical value of this field. There are metastable and stable states if one includes a small field parallel to the easy axis (hz). The motion of the relaxation front of the metastable state is investigated. It is found that an “interphase wall of Neel-type” exists, its velocity is proportional to hz and increases when the critical point is approached. |
