Abstract
Magnetic torque measurements offer a possibility of specifying texture in ferromagnetic materials in a quantitative fashion and several methods have been proposed for accomplishing this. The method of Akulov and Brüchatov, although formally correct, is shown to be so restricted by its assumptions as to be inapplicable even to the commonest texture. A method proposed by Bitter, involving root-mean-square deviations from some mean orientation, is found to fail in practice because of the uncertainty in the measurement of the magnetic energy. A modification of this method, in which x-ray data are used to establish a relationship between two of the root-mean-square deviations, gives results in fair agreement with the pole figure of a cold-rolled iron-silicon alloy.
