Abstract

One of the most important consequences of the recent theory of itinerant electron magnetism is that the average squared amplitude of the local spin density SL 2 varies generally with temperature depending on the band structure, the electron occupation and the relative strength of the exchange interaction [1]. Below the Curie temperature TC, SL 2 usually decreases with increasing temperature while it increases with temperature above TC. This temperature variation can be quite significant in many cases and reflects itself in the thermal expansion.
