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

The internal coercive field has been associated with the minimum force counteracting the motion of 180 deg 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.
