Abstract

This study investigated the magnetic field (H) dependence of thermal conductivity (κ) in type I (Pb) and type II (Nb) superconductors. The κ of Nb displayed hysteresis, showing a local minimum during increasing H process but not during decreasing H process. Different magnetic field dependencies were observed in Pb with varying purity: κ of 3N-Pb exhibited broad hysteresis, while that of 5N-Pb showed hysteresis similar to 3N-Nb.
