Using conductive atomic force microscopy, we observed non-uniform distributions of metallic and insulating domains on the surface of a single crystalline (La0.4Pr0.6)0.67Ca0.33MnO3 film grown on a (110) NdGaO3 substrate. The electronic properties of the surface exhibit thermal hysteresis. The hysteresis is similar to that of the transport and magnetism of the film bulk.
