Abstract

The temperature and the field dependence of the effective magnetic penetration depth ( \ensuremathλ_eff) in the vortex state of a d-wave superconductor, as measured by muon spin rotation ( \ensuremathμSR) experiments, is calculated using a nonlocal London model. We show that at temperatures below T^*\ensuremath∝√(B), the linear T dependence of \ensuremathλ_eff^\ensuremath-2 crosses over to a T³ dependence. This could provide an explanation for the low temperature flattening of the \ensuremathλ_eff^\ensuremath-2 curve observed in a recent \ensuremathμSR experiment.
