Summary

ThAsSe and UAsSe represent rare examples for non-magnetic Kondo systems. For deeper insight into this behaviour a compound with the same crystal structure type from the chemical system Zr–As–Se was studied extensively in terms of chemical composition, crystal structure and electrical resistivity at low temperatures. The results indicate the unusual behaviour of ZrAs_1.4Se_0.5 to be connected with dynamical phenomena within the anionic substructure.
