用静态磁化强度、交流磁化率和磁阻测量方法研究了UPd_2Al_3单晶的正常和超导性质。在正常状态下，饱和磁电阻沿[0001]方向存在沿着的开路轨道。在超导状态下，一个明显的峰值效应被观察到低于上临界场H-c2。在低温下，该峰由两个结构组成，在0.6K以上变为一个结构，并一直延续到0.1T的低场。这些实验结果进行了比较的基础上的FFLO模型。通过静态磁化强度的测量，发现了超导中的顺磁效应。
Normal and superconducting properties of single crystalline UPd2Al3 have been studied by static magnetization, AC susceptibility and magnetoresistance measurements. In the normal state, an open orbit is found to exist along the [0001] direction h-om a saturated magnetoresistance. In the superconducting state, a pronounced peak effect is observed just below the upper critical field H-c2. The peak consists of two structures at low temperatures, becomes one above 0.6 K and continues up to a low field of 0.1 T. These experimental results are compared to those based on the FFLO model. The paramagnetic effect in superconductivity is also found by the static magnetization measurement.
