On the Magnetic Properties of Single Crystals of Iron

Abstract

FORMERLY the preparation of single crystals of iron has been made by Goldschmidt's method, by which means crystals ranging from one to two centimetres in linear dimensions can be obtained; but the production of larger crystals by the same method is almost impossible. In 1924, however, Prof. C. A. Edwards obtained large crystals of iron by using Prof. Carpenter's method of preparing single crystals of aluminium, and thus opened to us an important route for the investigation of the true nature of the metal. Hitherto we have been able to measure only the mean of the properties differing in various orientations of the crystal, but we are now in a position to study the property of an individual crystal in different directions relative to its orientation.
