Abstract: We have performed the muon spin rotation (SR) measurements of the magnetic penetration depth λ in the superconducting ceramical samples BaPb1−xBixO3 with the bismuth content x=0.22, 0.24, 0.26. The magnetic penetration depth has the low temperature value λ(4.3K) = 7900A for x=0.24. The temperature dependence λ(T)−2 have linear behaviour without any saturation down to the temperature 4.3 K.
