摘要
利用磁控溅射，将磁电阻材料Ｌａ０．６７ Ｃａ０．３３ＭｎＯ３（Ｔｃ＝ ２６７℃）与金属Ａｇ、Ｆｅ 等材料相结合，制成了多层膜（磁电阻材料／非磁金属／铁磁金属），测得了三层膜“Ｌａ０．６７ Ｃａ０．３３ＭｎＯ３／Ａｇ／Ｆｅ”的巨磁电阻效应（ＭＲ＝ ８６％ ，Ｂ＝ ０．８Ｔ，Ｔ＝ １５０Ｋ）．
A new multilayed structure of “La 0.67 Ca 0.33 MnO 3/Ag/Fe” has been prepared by magnetron sputtering and vaccum evaporation. Colossal magnetoresistance ratio exceeding 86% at B=0.8T has been found in the sample and such value is larger than optimized epitaxial thin film La 0.67 Ca 0.33 MnO 3.
