The complex susceptibility of a sintered Y-Ba-Cu-O superconductor is strongly dependent on a.c. field amplitude, h. Very small values of h must be used for the real part of susceptibility, Z', to reach a value corresponding to bulk diamagnetism just below the critical temperature, T c. The imaginary
