摘要：

Tetravalent praseodymium perovskite, BaPrO3, was prepared, and its magnetic susceptibility was measured in the temperature range between 4.2 K and room temperature. Magnetic ordering was found at 11.5 K. A very sharp decline of the susceptibility was observed when the temperature was increased through this transition temperature. Magnetic susceptibilities of BaPr1-yCeyO3 solid solutions were also measured. Electron paramagnetic resonance (EPR) spectra could be measured only at 4.2 K for the sample of praseodymium ion doped in diamagnetic BaCeO3. The spectra were complicated. The results of magnetic measurements show that the praseodymium ion is in the tetravalent state. © 1993 Academic Press. All rights reserved.
