１９９３年发现，钙钛矿结构稀土过渡金属的氧化物的磁电阻可达１０’一１０’％称之为庞磁电阻（Ｃｏｌｏｓｓａｌｍａｇｎｅｔｒｅｓｉｓｔａｎｃｅ）．这类氧化物材料，特别是它们的薄膜，在制备高密度磁数据存储器件和磁传感器等方面有十分重要的应用价值，因而受到人们的
In 1993, it was found that the magnetoresistance of perovskite rare earth transition metal oxides can reach 10 ’-10%, which is called colossal magnetoresisistance. Such oxide materials, particularly their thin films, are of great importance in the fabrication of high-density magnetic data storage devices and magnetic sensors and are therefore of interest
