Exchange interaction and magnetoresistance in La2/3Ca1/3MnO3: experiment and models Academic Article uri icon


  • The magnetization M(T) and electrical resistivity ρ(T) of a La 2/3Ca1/3MnO3 film have been studied in the temperature range 5K≤T≤320K in the magnetic field intervals 10Oe≤H≤400Oe and 0≤H≤50kOe, respectively. It is found that the M(T)/M(0) value is larger than that predicted by the conventional molecular field model below the Curie point T=267K, and that the lnρ(T) dependence is close to linear in the temperature range 80K
