Abstract
The differential equations for the minimal energy state of a one-dimensional 90° wall in an infinite cubic crystal are used to establish two self-consistency criteria for Ritz models of such a wall, or for its computation. Numerical minimization of the energy is carried out for the physical parameters of Fe, but with various values of Ms. The results show a structure with very little surface charge (a ‘‘Néel wall’’) for rather small Ms. This turns (via some intermediate structures with a mixed charge) to one that has almost only surface charge (a ‘‘Bloch wall’’) for larger Ms (such as the actual value in Fe).This publication has 8 references indexed in Scilit:
