Abstract

The magnetizations (M-perpendicular to) of strips of BiSCCO tapes are seen to evolve towards a common diamagnetic (M-perpendicular to) versus H-perpendicular to curve, hence display quasi-reversibility, from the application of a few cycles of a magnetic field H-parallel to directed along their length, when previously magnetized, (i) to critical paramagnetic or diamagnetic states along the major hysteresis loop by an excursion of a transverse magnetic H-perpendicular to piercing the flat surfaces and now held fixed or, (ii) by field cooling in static H-perpendicular to. The remanent magnetic moment along H-parallel to when the cycling ceases is made to vanish by a simple demagnetization procedure which homogenizes the flux trapped along H-parallel to.
