We report here on the electron spin resonance (ESR) study of paramagnetic probe adsorbed on the surface of K-doped polycrystalline Bi2Sr2CaCu2-xKxO8+δ (x = 0.5-0.7) carried out in the temperature range 77-300 K. The TcS of the samples found to increase with Cu (K) subtraction (addition). From the Brandt's model for triangular vortex lattice, the widths of the observed ESR lines below Tc are related to the penetration depth. From the analysis of temperature dependence of A, penetration depth at zero temperature (λ0) is estimated. The results are explained using BCS clean limit and dirty limit models.
