Abstract
Magnetic moment measurements on niobium/copper multilayers by means of a torque magnetometer exhibit a series of maxima at specific field st rengths H(N) when the applied magnetic field makes a small angle with the plane of the superconducting layers. These maxima are shown to be closely related to rearrangements of the parallel vortex system, durin g which an increasing number of vortex chains is formed in the sample.
