Descrição: Specific heat measurements on superconducting Lu sub(2)-Fe sub(3)Si sub(5) reveal a strong sample dependence of the residual specific heat contribution gamma sub(s), below T sub(c), effectively ruling out the possibility of a two-band model. Upper critical field H sub(c2) results for Lu sub(2)Fe sub(3)Si sub(5), Sc sub(2)Fe sub(3)Si sub(5), and LaFe sub(4)P sub(12) show a very large H sub(c2) with an unusual temperature dependence for Lu sub(2)Fe sub(3)Si sub(5), in contrast to the latter two compounds, implying a strongly sample-dependent H sub(c2) as well. Intrinsic magnetic impurities arising from structural disorder and defects are possibly the origin of these anomalous superconducting state properties of Lu sub(2)Fe sub(3)Si sub(5).
