· J. Less-Common Metals
Step-type anomalies in the electrical resistivity between 4 and 5 deg K found in holmium, erbium, thulium, and lutetium, contaminated with tantalum, are described. The results are discussed in terms of the concept of superconducting filaments formed by tantaluta. Some other features of the electrical resistivity (hysteresis effects above critical temperature of tantalum, resistivity minimum) also observed in certain cases are described and are difficult to understand from the viewpoint of a superconductivity substructure. It is possible that in special cases some cooperative magnetic ordering occurs that is responsible for the observed effects. Some experiments, which should clarify the proposed models, are suggested.
