| 摘 要： | 本文给出了Ti-Pd系合金样品的低温比热的测量结果,得出样品Ti0.92Pd0.08及Ti0.8Pd0.2的电子比热系数r分别为5.89mJ/mol·K2和4.78mJ/mol·K2,显然比纯Ti的r值3.32mJ/mol·K2高得多。因此,它们的费密面的电子态密度也比纯Ti的高,这正是Ti-Pd系合金的超导转变温度Tc比纯Ti的有较大幅度提高的原因。

| Abstract: | The specific heats of Ti-Pd alloys have been measured between 1-6 K, and the electronic specific heat coefficients γ of samples Ti0.92Pd0.08 and Ti0.8Pd0.2 are found to be 5.89 mJ/mol·K2 and 4.78mJ/mol·K2 respectively, which are obviously higher than 3.32mJ/mol·K2 of pure Ti. Therefore, the densities of states at Fermi surface for these alloys are higher than that of pure Ti, this is the reason why the alloys have much higher superconductive transition temperature Tc than pure Ti. |
