Abstract

Muon spin relaxation measurements in the layered superconductor NbSe₂ have been performed to study the magnetic field penetration depth λ. The relaxation rate σ(T) α λ(T)^-2 in field-cooled measurements exhibits a temperature dependence consistent with an isotropic energy gap without anomalous zeros. The low temperature penetration depth λ(T → 0) = 2,500 A ̊ is much larger than that obtained from previous H_c1 measurements.
