In 1986 George Bednorz and Karl Alex Muller ¿ made the remarkable discovery ofsuperconductivitywithanunbelievinglyhighvalueofT = 35K,bysubs- c 2+ 3+ tuting Ba ions for La ions in the antiferromagnetic insulator La CuO . 2 4 Soon after this discoveryT rose to 90K by synthesizing YBa Cu O with c 2 3 7?? ade?citinoxygen. Furtherexplorationfornewcopperoxidesuperconducting materials with higherT led to the discovery of Bi¿Sr¿CäCu¿O, Tl¿BäCä c Cu¿O and Hg¿BäCäCu¿O compounds in subsequent years. The new class of copper oxide compounds mentioned above is called ¿cuprates¿. At present T = 135K under ambient pressure andT = 164K under 31 GPa observed c c in HgBa Ca Cu O are the highest value so far obtained. The Kamimurä 2 2 3 8 Suwa model, which was originally developed in 1993, is a theory of these real copper oxide superconducting materials. Since undoped La CuO is a 2 4 Mott¿Hubbard antiferromagnetic insulator, its electronic structure can not beexplained bytheordinaryone-electron energybandtheory. Inthiscontext the important role of electron-correlation was pointed out. 2+ On theother hand, ad-hole state in each Cu ion in theligand ?eld with octahedral symmetry is orbitally doubly-degenerate so that it is subject to strong Jahn¿Teller interaction in La CuO. Asaresult,aCuO octahedron 2 4 6 in La CuO is elongated along thec-axis due to the Jahn¿Teller distortion.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783540251897\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783642064340\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Hardcover - 9783540251897","offer_id":51306594694,"sku":"9783540251897","price":106.99,"currency_code":"EUR","in_stock":true},{"title":"Softcover - 9783642064340","offer_id":39437504020573,"sku":"9783642064340","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5016ea69-b1fb-42f0-ad84-46419c8fa62e.jpg?v=1782537230","url":"https:\/\/shop.autorenwelt.de\/products\/theory-of-copper-oxide-superconductors-von-tsuyoshi-hamada-hiroshi-kamimura-shunichi-matsuno-hideki-ushio","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
