Magnetic properties of high-Tc superconducting oxides were investigated by ac-complex magnetic susceptibility X = X'-jX". The magnetic penetration depth ,,(T) obtained f 2 0m X' was analyzed by the term of BCS gap parameter. A strong correlation between Tc and ,,(0)-was found. The loss peak of X"(T
