Modern Theory of Magnetism in Metals and Alloys

This book describes theoretical aspects of metallic magnetism from metals to disordered alloys to amorphous alloys both at the ground state and at finite temperatures. Explores the topic via spin-fluctuation theories based on the functional integral method.

This book describes theoretical aspects of the metallic magnetism from metals to disordered alloys to amorphous alloys both at the ground state and at finite temperatures. The book gives an introduction to the metallic magnetism, and treats effects of electron correlations on magnetism, spin fluctuations in metallic magnetism, formation of complex magnetic structures, a variety of magnetism due to configurational disorder in alloys as well as a new magnetism caused by the structural disorder in amorphous alloys, especially the itinerant-electron spin glasses. The readers will find that all these topics can be understood systematically by means of the spin-fluctuation theories based on the functional integral method.
