Disorder-sensitive superconductivity in the iron silicide Lu${}_2$Fe${}_3$Si${}_5$ studied by the Lu-site substitutions

T. Watanabe, H. Sasame, H. Okuyama +2

We studied effect of non-magnetic and magnetic impurities on superconductivity in Lu${}_2$Fe${}_3$Si${}_5$ by small amount substitution of the Lu site, which investigated structural, mag…
