Two-gap superconductivity in R2Fe3Si5 (R=Lu, Sc) and Sc5Ir4Si10

Two-gap superconductivity in R2Fe3Si5 (R=Lu, Sc) and Sc5Ir4Si10

R2Fe3Si5 (R= Sc, Y, Lu) contains nonmagnetic iron and has a relatively high superconducting transition temperature Tc among iron-containing superconductors. An anomalous temperature dependence of specific heat C(T) has been reported for polycrystalline samples down to 1 K. We have grown R2Fe3Si5 sin...
