Two-gap superconductivity in single crystal Lu${}_2$Fe${}_3$Si${}_5$ from penetration depth measurements

R. Gordon, M. D. Vannette, C. Martin +3

Single crystal of Lu${}_2$Fe${}_3$Si${}_5$ was studied with the tunnel-diode resonator technique in Meissner and mixed states. Temperature dependence of the superfluid density provides s…
