The interesting phenomenon ferromagnetism is much from being totally understood, even though it absolutely belongs to the oldest difficulties of strong nation physics. For any research it seems that recommendable to differentiate among fabrics whose spontaneous magnetization stems from localized electrons of ?lled atomic shell and people within which it's as a result of itinerant electrons of ?lled conduction band. within the latter case one speaks of band-ferromagnetism, prototypes of that are the classical ferromagnets Fe, Co, and Ni. the current ebook is a standing file at the striking development that has lately been made in the direction of a microscopic figuring out of band-ferromagnetism as an electron c- relation e?ect. The authors of some of the chapters of this publication “Band-Ferromagnetism: Ground-State and Finite-Temperature Phenomena” participated as chosen - perts within the 242nd WE-Heraeus-Seminar (4-6 October 2000) held lower than nearly an identical name in Wandlitz close to Berlin (Germany). It was once the second one seminar of this sort in Wandlitz. (The ?rst in 1998 handled the complementary subject of the physics of local-moment ferromagnets comparable to Gd). Twenty-six invited spe- ers from ten di?erent international locations including ?fty-?ve additional members, who awarded contributions in kind of posters, spent 3 days jointly discussing in an enthusiastic and fertile demeanour the new themes of band-ferromagnetism.
