摘要：

The magnetic, electric, and dielectric properties of a B-site ordered double perovskite Pr2CoMnO6 were investigated. A charge localization state and a negative magnetoresistance effect were observed below 250 K. Different from other double perovskites, one negative and two positive magnetodielectric effects were simultaneously observed in this sample. The physical origins of these interesting magnetodielectric properties were discussed.
