Three-dimensional Fermi surface and small effective masses in Mo 8 Ga 41
Abstract
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 quastiparticle 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 new materials in this class could be of interest for superconducting wire applications.
