Abstract

Abstract We have reexamined the magnetic behavior of BaPrO 3 in the temperature range 4.2 < T < 300 K. An anomaly in the susceptibility at 11.6(1) K has been observed, and is attributed to the onset of long-range ordering of the Pr 4+ f-electrons. Above the critical temperature, the paramagnetism is composed of a temperature-dependent term with an effective moment of 0.7(1) μ B and a temperature-independent term of 6.9(2) × 10 −4 emu/mole. Calculations based on a simple crystal field model explain the low effective moment found experimentally.
