  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.
