This controversy sterns from the apparent dual character of the d-electrons responsible for magnetism in transition metals, i.e., they are itinerant elec- trons described by band theory in their ground state, while at finite tem- peratures they show various properties that have long been attributed to a system consisting of local magnetic moments. The most familiar example of these properties is the Curie-Weiss law of magnetic susceptibility obeyed by almost all ferromagnets above their Curie temperatures. At first the problem seemed to be centered around whether the d-elec- trons themselves are localized or itinerant. This question was settled in the 1950s and early 1960s by various experimental investigations, in particular by observations of d-electron Fermi surfaces in ferromagnetic transition metals. These observations are generally consistent with the results of band calculations. Theoretical investigations since then have concentrated on explaining this dual character of d-electron systems, taking account of the effects of electron-electron correlations in the itinerant electron model. The problem in physical terms is to study the spin density fluctuati-ons, which are ne- glected in the mean-field or one-electron theory, and their influence on the physical properties.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Toru Moriya\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 364282501X\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783642825019\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Springer\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 11\/10\/2012\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 242\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.80lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.21h x 6.14w x 0.54d","brand":"Toru Moriya","offers":[{"title":"Paperback","offer_id":43940824711423,"sku":"9783642825019","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_c06593c8-50c1-41ee-a315-8d0e49f745ba.jpg?v=1681449383","url":"https:\/\/www.whiterainbookhouse.com\/products\/spin-fluctuations-in-itinerant-electron-toru-moriya-9783642825019","provider":"WR Book House","version":"1.0","type":"link"}
