Measurements are reported on the superconducting properties of V/Fe superlattices showing the interplay between ferromagnetism and superconductivity. When the V layer thickness is on the order of the BCS corherence length and the Fe layer is only a few atomic planes thick, a 2D-3D crossover is observed in the temperature dependence of the parallel upper critical field H-italic/sub c-italic//sub 2//sub parallel/. This implies the coexistence of superconductivity and ferromagnetism in the Fe layers. Three-dimensional behavior for thinner Fe layers is observed (--1 atomic plane) and 2D behavior for thicker Fe layers (>10 atomic planes).
