Description
The magnetoresistance (MR) and magnetization of La2/3Ca1/3MnO3 films with controllable grain sizes have been studied. Both quantities show differences between their zero-field cooled (ZFC) and field cooled (FC) states at low temperatures. The results indicate the coexistence of two types of spin glass phase at and nearby the grain boundaries: one forms a shell of a certain thickness and manifests itself in both MR and magnetization, and the other is nearly volume-less, manifesting itself only in MR
