摘要：

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.
