摘要：
The results of neutron diffraction studies of the effect of the isotopic substitution 16O → 18O in Sm1 − xSrxMnO3-type (x = 0.45 and 0.50) manganites are considered. The parameters of the crystal and magnetic structures of the samples are determined in the temperature range 1.4–300.0 K. It is shown that the isotopic substitution considerably changes the phase diagram of manganites. The results of the earlier macroscopic studies of the same samples are confirmed.
