Description
The field amplitude and frequency dependent complex ac susceptibility χ(Hm,f) of three Y-Ba-Cu-O disks made by a top-seeded melt growth technique has been measured at 77 K with the ac field applied along the c-axis of the samples (parallel to their thickness). A procedure based on the Bean model has been developed to calculate the critical-current density Jc near the surface of the sample from the measured χ(Hm) for the case where the maximum imaginary component χ'' is not reached
