自从Jin等人发现氧化物薄膜中存在令人惊讶的巨磁阻(giant magnetoresistance,GMR)效应后,这类氧化物材料引起了人们极大关注。现已清楚,锰离子(Mn~(3+)/Mn~(4+))
Since Jin et al. Discovered the surprising giant magnetoresistance (GMR) effect in oxide films, such oxide materials have drawn great attention. It is now clear that manganese ions (Mn ~ (3 +) / Mn ~ (4+))
