Abstract: The lower critical field Hc1 (T) of superconductor was studied with the zero-field non-resonant absorption signals by ESR method. The experimental values of Hc1 (T) accord with Hc1 (T)=Hc1 (0)(1-T2/Tc2). The reason for the increase of Cu2+ ESR signal intensity with doping is also discussed.
