液氮温区金属钆（Gd）热导率研究

Study of the Thermal Conductivity of Gadolinium at the Liquid Nitrogen Temperature Range

详细介绍小样品热导率测量装置，用该装置测定了沪产９９．９％纯钆的热导率。发现在２３０Ｋ附近轧热导率反常，趋向极小。证实了除电子以外，磁机制对钆电导和热导有较大贡献。

A thermal conductivity measuring apparatus for small samples has been developed. The thermal conductivities of Gd with a purity at 99.9%which is made in Shanghai has been measured.An abnonmality has been di-scovered-the thermal conductivities of Gd tends to minimum.This indica-tion is that in addition to electrons some magnons heat transport has effe-ct on the thermal conductivity.
