摘要：

We have measured specific heat, magnetic susceptibility and electrical resistivity of UPd2Al3 and UPd2Al3.03 single crystals. The temperature dependence of the specific heat of UPd2Al3 reveals that the superconducting gap function is anisotropic. We present the results of specific heat measurements of UPd2Al3.03, suggesting an additional phase transition around 0.6 K.
