摘要

本研究调查了 I 型（铅）和 II 型（铌）超导体中热导率（κ）与磁场（H）的关系。Nb 的 κ 显示出滞后性，在 H 值增加过程中出现局部最小值，而在 H 值减小过程中则没有。在纯度不同的铌中观察到了不同的磁场依赖性：3N-铌的κ表现出宽滞后，而 5N-Pb 的κ表现出与 3N-Nb 相似的滞后。

Magnetic Field Hysteresis of Thermal Conductivity in Type-I and Type-II Superconductors

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.
