✦ Synopsis

Substituted effects on superconducting and magnetic states of Tm 5 Rh 6 Sn 18 were examined by doping Y or Co element. In Y-20% doped material, superconductivity was destroyed above 3.0 kOe with developing magnetic ordering. After destroying superconductivity, electrical resistivity decreased with decreasing temperature again. In addition, magnetic field, which was possible to destroy superconductivity, was higher than that of parent compound. In Co-20% doped material, the magnetic field, destroying the superconductivity, was weaker than that of parent compound. From these results, we concluded that Tm-site was responsible for magnetic properties and Rh-site played a main role for superconductivity.
