The magnetization M(T) and electrical resistivity ρ(T) of a La₂/₃Ca₁/₃MnO₃ film have been studied in the temperature range 5 K⩽T⩽320 K in the magnetic field intervals 10 Oe⩽H⩽400 Oe and 0⩽H⩽50 kOe, respectively. It is found that the M(T)/M(0) value is larger than that predicted by the conventional m...
