Abstract
For the study of magnetic properties of sintered high-Tc ceramic superconductors, we measured harmonic ac susceptibilities Xn = Xn'-iXn” of Bi1.6Pb0.4Sr2Ca2Cu3Oy immersed inan external field H(t) = H'dc + Haccos(Öt), where Hdc (0) is a dc bias field and Hac (> 0) is an ac field amplitude. Measurements of Xn were carried out for n = 1, 2, 3, 5, 7, 9 and OHac = 0.01-0.1 mT. The fundamental frequency used was 132 Hz. The observed results wereanalyzed within the construct of the Kim-Anderson model for critical-current density. Similar to our previous work for an YBa2Cu3Oy sample with Fe impurities, generation of the higherharmonic susceptibilities seems to arise from the supercurrent according to the same model. Details of the measurement and the analysis are presented.
