180-DEGREES DOMAIN-WALL WITH THE COORDINATE DEPENDENT AZIMUTHAL ANGLEOF MAGNETIZATION

Structure of 180 degrees one-dimensional domain wall (DW) in a uniaxia l ferromagnet in the presence of an external magnetic held arbitrarily oriented with respect to the DW has been investigated. Solutions of t he system of equations which describe the behavior of the magnetic mom ent inside the DW in the case when the magnetization azimuthal angle i s dependent upon the coordinate normal to the DW have been obtained an d influence of magnetic field on the structure of the DW analyzed. Dep endences of the effective widths of the distributions of both the pola r and azimuthal angles of magnetization across the DW proper have been obtained. The effective width due to the azimuthal angle variation al ong the DW normal was found to increase with increasing transverse fie ld. (C) 1996 American Institute of Physics.
