Description
Magnetization cycles and relaxation measurements as a function of temperature and field are reported for a very thin Bi2Sr2CaCu2O8+x single crystal (thickness 5 μm). The fishtail effect was observed between 15 and 26 K at about 400 Oe, at which the relaxation rate was also found to increase rapidly. The observed behaviour is attributed to the field-induced two-dimensional to three-dimensional crossover in the vortex lattice in the presence of bulk pinning and surface barriers which dominate in different regions of the B-T phase diagram.
