We report the low temperature specific heat of ternary iron-silicide superconductor Lu 2 Fe 3 Si 5 with T c = 6 K down to $T c /20. We find that a normalized specific heat jump at T c , DC/c n T c , is smaller than BCS value of 1.43. We also find that the specific heat divided by temperature C/T sho

We report detailed study of non-magnetic impurity effects in a two-gap superconductor Lu 2 Fe 3 Si 5 by replacing Lu with Sc. We find that the superconducting transition temperature T c is drastically suppressed by slight substitution of Sc, while lattice constants change linearly with the substitut
