Abstract
We report the results of magnetisation measurements of Bi2Sr2CaCu2O8+delta single crystals. Hysteresis loops are compared using scaling analysis and the possible origin of the 'arrowhead' anomaly in the m-H behaviour is discussed. The irreversibility line (IR) is determined between 55K and 4.2K and is shown to vary with temperature exponentially over two distinct thermal ranges. These results are interpreted by considering the influence of temperature and distribution of pinning site strengths on the dimensionality of the vortex lattice. The 'arrowhead' anomaly and rapid drop in the irreversible magnetisation at about 20K are suggested to be intrinsic features of the critical state behaviour in the presence of a dimensional crossover in extremely anisotropic HTS materials.
