Abstract
We present the field dependence of the magnetic moment on Nb/Al multilayers for applied field parallel and perpendicular to the multilayer surface. Zero-field cooled magnetization versus applied magnetic field (ZFC M versus H) curves, for the parallel applied field geometry, presents a series of maxima at both virgin and downward branches, the number of which being diminished as T c is approached. Strong evidence of matching effects of the vortex lattice to the layered structure of the multilayer is revealed by the presence of well-defined plateaus, at the magnetization peaks positions, in magnetic induction ( B) versus H curves. The jumps in magnetic induction are associated with the sudden splitting up of the in-plane vortex rows during rearrangement. At the perpendicular field geometry, we have found an extremely noisy behavior in a specific region in the magnetization curve also for both upward and downward branches. This suggests the occurrence of instabilities in vortex penetration in that field range.
