Abstract
Statistical Rayleigh-curve theory is applied to thin evaporated MnBi films in order to obtain information concerning the density of wall pinning centra. The treatment results in a prediction of the coercive forceH c and the average distance between adjacent wall pinning centra, 2L 0. The coercive forceH cis also measured experimentally. The results of the two methods are in good agreement with each other.
The influence of dislocations on the coercive force is discussed briefly.
