在293°~1200°K和90°~1200°K温度范围内，测量了一系列淬火γ体心立方铀钼合金的磁化率和电阻率。U-15、20、25at.%Mo在亚稳γ态具有较小的负电阻率温度系数，在稳定γ区有正电阻温度系数。所有样品都表现出随温度升高的泡利弱自旋顺磁性，并且在15-30at.%Mo范围内具有与组成无关的交换贡献。讨论了这些结果对我们理解γ合金电子结构的影响。
The magnetic susceptibilities and electrical resistivities of a series of quenched γ body-centred cubic uranium-molybdenum alloys were measured over the temperature ranges 293°-1200°K and 90°-1200°K, respectively. U-15, 20, 25 at.% Mo each possessed a small negative temperature coefficient of resistivity below about 200°C in the metastable γ-state, and a positive coefficient in the stable γ-region. All samples exhibited a Pauli weak spin paramagnetism which increased with temperature, and in addition possessed an exchange contribution shown to be independent of composition over the range 15-30 at.% Mo. The bearing of the results on our understanding of the electronic structure of the γ-alloys is discussed.
