摘要：

Maxima in curves of critical current vs. temperature at fixed fields have been found to be associated with the peak effect in a 5Nb at. % Ti strip. The data are in qualitative accord with recent suggestions that a superconductor with π{variant}Jc/π{variant}T·0 should show unusual stability. The ratio of the field at the peak to the upper critical field was found to be independent of temperature, having a value 0·84. There is an indication that the dependence of thermal conductivity on temperature is anomalous in the region of the maxima. © 1969.
