Magnetic, electrical and thermal properties of heavy fermion superconductor UPd/sub 2/Al/sub 3/

We report experimental results of electrical resistivity, de Haas-van Alphen effect, specific heat and thermal expansion of UPd/sub 2/Al/sub 3/. The nominal composition is denoted by the formula of UPd/sub 2+x/Al/sub 3+y/. Samples with the composition of UPd/sub 2/Al/sub 3.03/ and UPd/sub 2.02/Al/sub 3.03/ reveal de Haas-van Alphen oscillations of the magnetic susceptibility. An anomaly is observed in the superconducting phase in the temperature dependence of the specific heat and thermal expansion of UPd/sub 2/Al/sub 3.03/. The relation between the sample quality and the appearance of the anomaly is discussed. >
