Minimum force model. Effect of crystallographic texture on the magnetostriction and loss characteristics of non-oriented electrical steels

Abstract

The internal coercive field has been associated with the minimum force counteracting the motion of 180° Bloch walls, which depends on the relative orientation between the crystal axes and the magnetisation direction. The minimum force is related both to the texture-dependent components of the hysteresis loss and to the internal coercive field derived from the statistical loss model by Bertotti. Correlations have been also found with the fitting parameters of a previously presented magnetostriction model.
