Abstract

Results on the driving-field amplitude dependence of the AC-susceptibility of a Bi2Sr2CaCu2O8+ delta-single crystal measured in an applied DC magnetic field are presented. The data obtained in DC fields higher than 2.5T strongly support 2D plastic creep as determining the diamagnetic transition. At lower fields the susceptibility behaviour is more complex, although at all fields flux motion seems to be diffusive.
