| Abstract: | The resistivity, ρ(T), of thin film and bulk samples of La₀₇Ca₀₃MnO₃ is investigated in magnetic fields between 0-10 T and temperatures between 10-340 K. Metallic resistivity, ρlt(T)=ρr+ρ2T2+ρ4.5T4.5, is observed well below the metal–insulator transition (MIT) temperature TMI. For T>TMI, the resistivity is governed by the Shklovskii-Efros variable-range hopping mechanism, giving View the MathML source |
