Preparation of thin films of the Heavy Fermion Superconductor UNi2Al3 — •M. Jourdan, A. Zakharov, M. Foerster, and H. Adrian — Institut für Physik, Johannes Gutenberg Universität, 55099 Mainz

UNi2Al3 belongs to the heavy fermion systems which are of special interest due to their presumably unconventional superconductivity. The availability of epitaxial thin film samples of this compound would allow new experimental examinations like tunneling spectroscopy on planar junctions.
We attempt to prepare UNi2Al3 thin films by MBE deposition. First results show that the preferential growth direction is the crystallographic (110)-axis. Different substrate materials which might support this growth mode were found. Thin UNi2Al3 films are characterized by XRD, SEM and AFM as well as by measurements of the temperature dependent resistivity R(T).
