Mo8Ga41的三维费米面和小有效质量
Three-dimensional Fermi surface and small effective masses in Mo8Ga41
摘要：
本文报道了用量子振荡法测量的临界温度Tc = 10 K的双能隙超导体Mo_8Ga_（41）的费米面特性。四个主要的频率已经观察到相对较小的准粒子质量。主要频率的角度依赖性表明三维费米表面片。这证明了相对各向同性的超导状态，并且考虑到其相对高的Tc，表明对这类材料的搜索可能对超导导线应用感兴趣。
英文摘要：
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.
