AbstractAbstract
[en] The temperature dependence of the Hall resistivity of thin epitaxial UPd2Al3 films with low defect densities is investigated. It shows a minimum at 6 K for fields up to 12 T. This feature is attributed to the superposition of a coherence-derived low-temperature Hall coefficient and a skew-scattering contribution. Further implications on the Hall effect in the coherence regime of Kondo lattices are discussed

AbstractAbstract
[en] Highly c-axis oriented thin films of the heavy fermion superconductor UPd2Al3 were prepared by coevaporation of the constituent elements with independent rate monitoring of three sources in a molecular beam epitaxy system (MBE). Detailed X-ray and reflection high energy electron diffraction (RHEED) studies revealed the well ordered in-plane structure of the films deposited on sapphire substrates with different orientations. Onset of superconductivity was found up to Tcon = 1.8 K. (Author)

AbstractAbstract
[en] Highly c-axis oriented thin films of the heavy fermion superconductor UPd2Al3 were prepared by electron-beam coevaporation of the constituent elements in a MBE-system. The phase purity and structural quality of the films deposited on different substrate materials were investigated. For transport measurements the films were patterned by photoresist techniques and etched with diluted nitric acid. Investigations of the normal and superconducting transport properties were performed. The highest superconducting onset reaches 1.8 K. ((orig.))
