Anwendung von einem Magnetowiderstand mit geordneter Doppelperovskitestruktur und deren Herstellungsverfahren

摘要

A magnetoresistor with an ordered double perovskite structure is an oxide crystal which has an ordered double perovskite crystal structure represented by the general formula of A2BB'O6, wherein A stands for Sr atoms, B for Fe atoms and B' for Mo or Re atoms and wherein the Fe atoms and the Mo or Re atoms are alternately arranged and which exhibits negative magnetoresistive characteristics.
