TUNNELING AND POINT-CONTACT SPECTROSCOPY ON UPD2AL3 IN THE NORMAL-STATE

Tunneling and Point Contact measurements were performed on a single cr ystal of the new heavy fermion superconductor UPd2Al3 in the normal st ate above and below the antiferromagnetic ordering temperature. For a certain range of resistances, tunneling spectra show the opening of a gap of about 7 - 15 meV in the density of states along the ab-directio n, but not along the c- axis. However, this gap is also found in point contacts made along the c-axis, showing that the latter method is les s sensitive to anisotropy.
