摘要：

Charge ordering and antiferromagnetic transitions in Pr0.67Ca0.33MnO3 have been studied by resistivity, thermopower, magnetic susceptibility and capacitance measurements. Strong magnetic competition arising from the distorted perovskite structure leads to a complex behavior. The appearance of the charge ordering coincides with antiferromagnetism at approximate to 225 K, leading to a large capacitive response of the material. (C) 1999 Elsevier Science B.V.
