Abstract
The temperature and field dependences of the magnetic moment of [Nb(x)/Ni(y)]5 multilayers are reported. Small kinks in the phase boundary defined in field-cooled AC experiments exhibit an approximate period of 733 Oe, and persist to a DC field H=6.5 kOe applied parallel to the multilayer. A second group of cusp anomalies in DC magnetization are observed for H<100 Oe with approximate period 15-20 Oe. The absence of anomalies in perpendicular field and normal state data suggest they are due to finite-size effects expected when the superconducting layer is thinner than the magnetic penetration depth.
