Variable-temperature MFM/EFM study of (La/sub 1-x/Pr/sub x/)/sub 0.67/Ca/sub 0.33/MnO/sub 3/ thin films

Both ferromagnetic (FM) and charge-ordered domain structures of (La/sub 1-x/Pr/sub x/)/sub 0.67/Ca/sub 0.33/MnO/sub 3/ thin film were detected by magnetic force microscopy (MFM) and electric force microscopy (EFM) operated at low temperatures near the peak resistance temperature (T/sub p/). The in-plane-like FM domains of submicrometer size emerge below T/sub p/, and their magnetic interaction with an MFM tip becomes stronger as the temperature is reduced. Charge-ordered insulating regions have the strong electrostatic interaction with an EFM tip near T/sub p/, and the interaction correlates well with the temperature dependence of resistivity of the film.
