Abstract
We present a detailed study of the low-field minor hysteresis loops, a nd the harmonic generation in magnetization, in sintered samples of Bi -1.7(Pb)(0.3)Sr2Ca2 CU3O10. We report history effects as the Dc field is cycled and as the Ac field is varied. We find, however, a qualitati ve difference from similar studies in YBa2Cu3O7. We observe large harm onic magnitudes in a Dc field regime where history effects are small. This has a possible interpretation that the intergrain weak links are magnetically hysteretic even when the grains are almost reversible. Th is interpretation is in agreement with the recent measurements on hist ory effects in transport J(c).
