论文摘要
我们报告了MO8GA41的费米表面特性，这是一种从量子振荡测量值获得的具有临界温度TC = 10 K的两间隙超导体。相对较小的准粒子质量已经观察到了四个主要频率。主要频率的角度依赖性表明三维费米表面表。这说明了相对各向同性的超导状态，并且鉴于其相对较高的TC，它表明对该类别中的材料进行搜索可能是超导电线应用的感兴趣。
We report Fermi surface characteristics of Mo8Ga41, a two-gap superconductor with critical temperature Tc = 10 K, obtained from quantum oscillation measurements. Four major frequencies have been observed with relatively small quasiparticle masses. Angular dependence of major frequencies indicates three-dimensional Fermi surface sheets. This argues for a relatively isotropic superconducting state and, given its relatively high Tc, shows that a search for materials in this class could be of interest for superconducting wire applications.
