We present an approach that allows the reconstruction of the zero-field magnetic penetration depth λ₀ based on the results of muon-spin-rotation (μSR) experiments conducted in a superconductor in the vortex state. It was successfully applied to describe the μSR experiments in optimally doped (BiPb)₂(SrLa)₂CuO_6+δ (OP Bi2201). We found that in unconventional d-wave superconductors (such as OP Bi2201) only at relatively low magnetic fields [B/B_c₂≲10⁻³; B_c₂ is the upper critical field] the effective penetration depth λ_eff, obtained in μSR experiment, is a good measure of λ₀. The high-field data need to be evaluated accounting for both the nonlinear and the nonlocal corrections.
