Inhaltszusammenfassung
Epitaxial thin films of the unconventional heavy fermion superconductor UNi2Al3 we prepared by coevaporation of the elementary components in a molecular beam epitaxy system (MBE). The phase purity and structural quality of the films deposited on (0 1 0)- or (1 1 2)-oriented YAlO3 substrates were studied by X-ray diffraction and RHEED. The observed R(T) behavior is consistent with data obtained from bulk samples and proves the purity of the films. Superconductivity was found with transition te...Epitaxial thin films of the unconventional heavy fermion superconductor UNi2Al3 we prepared by coevaporation of the elementary components in a molecular beam epitaxy system (MBE).
