Penetration depth study of LaOs4Sb12 : multiband s-wave superconductivity

We measured the magnetic penetration depth λ(T) in single crystals of LaOs4Sb12 (Tc=0.74 K) down to 85 mK using a tunnel-diode-oscillator technique. The observed low-temperature exponential dependence indicates an s-wave gap. Fitting the low-temperature data to a BCS s-wave expression gives the zero...
