摘要：
Magnetization and susceptibility measurements have been performed on oxygen-isotope substituted (O-16 and O-18) samples of Pr0.7Ca0.3MnO3 under pulsed magnetic fields up to 35 T. Experiments were carried out within the temperature range 78 to 300 K. Magnetic-field-induced phase transition into ferromagnetic state has been obtained in both samples at temperatures up to 200 K. Isotope substitution has been proved to have a significant impact on the temperature and field of this transition. Phase diagrams of the samples obtained from magnetization measurements are presented.
