Magnetism in Crystalline Materials covers the applications of the theory of groups of cambiant symmetry and the physical properties of magnetically ordered crystalline solids. This book is divided into eight chapters; the first of which discusses the macroscopic properties of magnetic crystals. The structures of magnetically ordered crystals are then explained; this topic is followed by discussions on the theory of corepresentations; magnetic phase transitions; and the tensor properties of magnetic crystals. This text also looks into topics on electrons, lattice vibrations, and spin waves. This selection will be valuable to physicists and to others interested in the magnetism of crystalline materials.
