Effect of transition-metal substitution for Fe in superconducting Lu/sub 2/Fe/sub 3/Si/sub 5/

;
The effect of transition-metal substitution for Fe on the superconducting transition temperature, T/sub c/, of compounds Lu/sub 2/(Fe/sub 1-x/T/sub x/)/sub 3/Si/sub 5/, where T = Cr, Mn, Co, Ni, Ru, is reported. In every instance, T/sub c/ of the host compound Lu/sub 2/Fe/sub 3/Si/sub 5/ (T/sub c/ = 6.11 K) is reduced by the addition of other transition metals. An analysis of the data within the framework of the theory due to Kaiser suggests the depression of T/sub c/ is due to the formation of a nonmagnetic resonance state. 10 refs., 2 figs.
