摘要: 制造超导体钯铜合金的新方法是把铜注入钯,然后在室温下电解,将Pd-Cu合金再在液氮温度下注入氢,这样所得到的超导结构H/Pd55Cu45≈0.7可以达到最高的超导临界温度为17K。由于氢的浓度对该系统超导性的存在是关键,因此,我们仍用15N的共振核反应法研究这类合金中氢分布及其对超导临界温度的影响和作用。从而对探索这类超导体新方法提供有意义的信息。

Abstract: A new method of preparing superconducting PdCu alloy is ion-implanting Cu into Pd and subsequent electrolysis at room temperature, then hydrogen implanting at liquid nitrogen temperature. Thus we obtain the superconducting structure H/Pd55Cu45=0.7, which has the highest transition temperature of 17 K. The paper also gives some results of the distribution of hydrogen in the alloy and its effects on superconducting transition temperature, as well as experimental conditions, so that it provides some interesting informations about the investigation of the new method in preparing them.
