Abstract

Magnetization, thermal expansion and resistance measurements were performed on the perovskite manganese La_2/3Ca_1/3MnO₃ and (Nd_0.6Th_0.4)_2/3Sr_1/3MnO₃. The results indicate that spontaneous magnetostriction through spin-lattice coupling leads to anomalous thermal expansion and lattice striction. For La_2/3Ca_1/3MnO₃, the temperature corresponding to the maximum of resistance and Curie temperature shifts to higher temperature under an applied field. As for (Nd_0.6Tb_0.4)_2/3Sr_1/3MnO3, the temperature corresponding to the maximum of resistance shifts to higher temperature with the applied field, but the paramagnetic Curie temperature does not. We suggest that the shift of the magnetic transition temperature in perovskite manganese oxides is due to the spontaneous magnetostriction and forced magnetostriction.
