摘要 报告了标称纯金和铜在 3-273 K 温度范围内的等温能斯特-埃廷豪森系数 Qi 的结果。将结果与银的结果进行比较，并检查所有三种材料的电阻率和热电势，表明铜和金样品的 Qi 行为主要是铁磁杂质（最有可能是铁）的近藤散射；基于桑德海默-威尔逊理论的分析对此给出了令人信服的证实。
Abstract Results are reported on the isothermal Nernst-Ettinghausen coefficient Qi of nominally pure Au and Cu over the temperature range 3–273 K. Comparison of the results with those for silver, together with an examination of the resistivity and thermopower of all three materials, suggests that the behaviour of Qi for the copper and gold specimen is dominated by Kondo scattering by ferromagnetic impurities, most probably iron; an analysis based on the Sondheimer–Wilson theory gives convincing confirmation of this.
