To perform high precision measurements of the transport anisotropy, epitaxial, a*-oriented thin films of UPd2Al3 have been prepared on LaAlO3 (1 1 0) substrates. The critical temperature and the upper critical field are comparable to typical bulk values. In contrast to UNi2Al3, we observed only a weak anisotropy in directional resistivity measurements, especially no dependence of the superconducting transition temperature on the direction of the applied current. Hall effect measurements sho...To perform high precision measurements of the transport anisotropy, epitaxial, a*-oriented thin films of UPd2Al3 have been prepared on LaAlO3 (1 1 0) substrates. The critical temperature and the upper critical field are comparable to typical bulk values. In contrast to UNi2Al3, we observed only a weak anisotropy in directional resistivity measurements, especially no dependence of the superconducting transition temperature on the direction of the applied current. Hall effect measurements show two characteristic minima at and , which corresponds to features seen in earlier measurements on c*-oriented films.» weiterlesen» einklappen
