Abstract
The superconducting properties of Lu(2)Fe(3)Si(5) with T(c) = 6.1 K have been investigated using low-temperature transverse-field muon spin rotation (mu SR) and specific-heat measurements. The magnetic penetration depth at zero temperature, lambda(0), is 353(1) nm. The temperature dependence of the magnetic penetration depth lambda(T) is consistent with a two-gap s + s-wave model. Low-temperature specific-heat measurements on the same sample also show evidence of two distinct superconducting gaps.
