Itinerant Magnetism: Elemental Magnets

This lecture explores the properties of elemental magnets such as iron, cobalt, nickel, chromium, and manganese at different temperatures, discussing the challenges in explaining ferromagnetism and the role of exchange interactions based on orbital overlap. The instructor delves into the concept of spin glasses, the effects of doping localised moments, and the observed discrepancies in magnetization behavior. The lecture concludes by highlighting the significance of band structure in governing the ordering of magnetic moments in these elements.
