Figure 4

Temperature dependent resistivity (ρ) of (a) LCMO, (b) LCMO:10%-NiO, (c) LCMO:10% Co3O4, (d) LCMO:30%-NiO, and (e) LCMO:30%-Co3O4 films at applied magnetic fields of 0 T and 3 T. (f) Plots of adiabatic expression ln(ρ/T) vs 1/T for LCMO, LCMO:10%-NiO, and LCMO:10%-Co3O4 films at temperatures higher than TP and zero magnetic field, with the best fits. The insets are magnifications of the curves around TP.
