title: Colossal enhancement of magnetoresistance in La(0.67)Sr(0.33)MnO(3) thin films: possible evidence of electronic phase separation.
abstract: A gigantic three orders of magnitude change of resistivity in La(0.67)Sr(0.33)MnO(3) (LSMO) thin film, on application of magnetic field, has been observed. The transport and magnetic properties are characteristic of electronic phase separation between ferromagnetic metallic and antiferromagnetic charge-ordered insulating regions, unusual for a canonical double exchange system such as LSMO.
