摘要：

A comprehensive account of structural features in mixed Mn3+, Mn4+ perovskites, Pr1-xAxMnO3 (A = Ca, Sr, Ba) is given. The newly investigated Sr system was studied at various temperatures by X-ray and neutron diffraction, magnetic, and conductivity measurements. A low-temperature transition from the activated type to the degenerate type of conductivity was observed in the Sr system for x = 0.3-0.4. It occurs 20-60 K below the ferromagnetic Curie point. © 1992.
