Superconducting property of single crystalline UPd2Al3 has been studied by static magnetization, AC susceptibility and flux flow resistivity measurements. A pronounced peak structure is observed just below the superconducting upper critical field HC2. 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 results are compared to those based on the FFLO model.
