Abstract
The superconducting properties of Lu2Fe3Si5 with Tc=6.1 K have been investigated using low-temperature transverse-field muon spin rotation (μSR) and specific-heat measurements. The magnetic penetration depth at zero temperature, λ(0), is 353(1) nm. The temperature dependence of the magnetic penetration depth λ(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.
