采用固相反应法制备了YCrO3多晶样品，并首次制备了和Y0．9Pr0．1CrO3多晶样品，研究了其磁性质．在场冷模式下，外加磁场为100Oe时，Y0．9Pr0．1CrO3的磁化强度一温度关系曲线显示磁化反转的异常．在尼尔温度以下，随着温度的降低，磁化强度首先增加，在96K达到最大值，约0．230emu／g．之后磁化强度开始降低，在32K变为零值；并且在32K以下，磁化强度出现负值．这种现象解释为Pr离子的顺磁效应．
Y0.9Pr0.1CrO3 and YCrOa polycrystalline samples were prepared by solid state reaction and their magnetic properties have been studied. The magnetization- temperature （M- T） curve of Y0.9Pr0.1CrO3 exhibits negative magnetization in field-cooled model with applied field of 100 Oe. Below Nfel temperature, magnetization increases with decreasing temperature, then achieves the maximum （MMAx） Of 0. 230 emu/g at the temperature about 96K. Then magnetization begins to drop with further decreasing of tempetature, passes through a zero values at the temperature of 32K. This temperature called compensation temperature （Tcomp）. Below the Tcomp, magnetization becomes negative. This behavior is interpreted in paramagnetic effect of Pr ions.
