Magnetization and susceptibility measurements have been performed on oxygen‐isotope substituted ( 16 O and 18 O) samples of Pr 0.7 Ca 0.3 MnO 3 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.
