We have measured the magnetic and superconducting properties of V/Fe superlattices. It is observed that ultrathin Fe layers behave in a 2-D fashion when isolated by thick V layers; however, on thinning the V layers a magnetic coupling between the Fe layers has been observed. No dead Fe layers were seen. When the V-layer thicknesses were on the order of the BCS coherence length, superconductivity was observed. A 2-D--3-D crossover was observed in the temperature dependence of the parallel critical field when the Fe layers were only a few atomic planes thick, implying the coexistence of ferromagnetism and superconductivity.
