(Color online) Temperature (T) dependent resistivity (ρ) of LCMO (a), LCMO:3% STO (b), and LCMO:5% STO (c) films at applied magnetic fields of 0, 0.5, 1, 2, and 3 T. (d)The experimental data (shown as symbols) and the linear fitting results (shown as solid lines) of ln(ρ/T) ∼ 1/T for LCMO, LCMO:3% STO, and LCMO:5% STO films at temperatures higher than T p and zero magnetic field.
