✦ Synopsis

A new magnetic superconductor Er2Fe3Sis was found by electrical resistivity measurements down to 0.1 K. The zero resistivity was attained at T¢0 = 0.47 K below incommensurate and commensurate amtiferromagnetic transition at 2.8 and 2.4 K, respectively. The upper critica2 field H¢2 is determined from a midpoint of the resistive transition. The initiM slope of Hc2(T) at T¢ is obtained to be -1.9 kOe/K. Hc2(0) is estimated to be 1.3 kOe from the WHH curve fitting. The coherence length is estimated to be ~0 = 500 A.

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
