We report experimental results of the electrical resistivity and the specific heat of UPd2Γ·xAia+r(nominal) single crystals. An anomaly in the specific heat, which was reported previously, has disappeared in the present measurement, although there still exists an anomaly in the thermal expansion. The

Elastic constants and thermal expansion on UPd2Ala have been measured. Elastic constants exhibit anomalies around TN = 14.5 K and T~ = i.8 K. Anomalous behaviors around 0.6 K in C~ ~, C3~ and thermal expansion are consistent with previous specific heat measurements. Superconducting Griineisen consta
The following issues concerning UPd2A13 are addressed: (i) its anisotropic magnetic phase diagram which can be explained by domain-reorientation effects, (ii) the coexistence between magnetically ordered local 5f moments and Cooper pairs formed by weakly delocalized 5f states and (iii) distinct anom
