摘要:

A one‐dimensional model with four adjustable parameters is assumed for the Ne´el wall separating two oppositely magnetized domains in a thin ferromagnetic film. It yields an energy which is somewhat lower than in any of the published models. Its self‐consistency parameterSis not very sensitive to changes in the anisotropy constant; and, for the parameters usually used for Permalloy films, thisSvaries between 0.94 and 1.23, which is a necessary condition that the wall energy thus calculated is reasonably close to the true, three‐dimensional minimum. It turns out that almost the same results can be obtained by choosing convenient values for two of the four parameters, and adjusting only two.
