摘要：

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.
