The hybrid superconducting/ferromagnet (S/F) heterostructures are intensively studied objects due to the presence of a large number of interesting and promising properties in them [1]. In the last years the focus has shifted to the study of simple S/F bilayers and S/F/S or F/S/F trilayers. At the same time we may expect that properties of a more complex S/F systems, like [S/F]n superlattices will differ from the properties of their constituent S/F bilayers. Such a difference is expected when the thicknesses of the layers become comparable with the correlation length of superconductivity and magnetism in the respective layers [2-5]. In a sense such superlattices can be considered as metamaterials assembled from “atoms” of S/F bilayers. In this report we present the first results on the creation and characterization of SF superlattices. The structures are assembled from CuNi/Nb bilayers investigated before in detai [6, 7]. There are several reasons for this choice of materials, like very small but non-vanishing solubility of CuNi and Nb (yielding smooth interfaces), good electrical contact and relatively high superconducting correlation lengths  S,F~ 10nm. Using of polarized neutron reflectometry and SQUID magnetometry we have found long range interlayer coupling of the CuNi ferromagnetic layers which exists in a wide range of thicknesses of Nb-spacers from 1 nm to 15 nm. This coupling arises due to the competition of dipole-dipole interlayer exchange interaction and magneto-crystalline energy. By applying a magnetic field in-plane, the moments of neighbouring CuNi layers gradually turn from antiparallel at remanence to parallel in saturation. Such a control of the vector magnetic state allows us to generate longrange triplet correlations in the whole system. The magnetic and transport data measured in the vicinity of the superconducting transition for different magnetic configuration will be also present.
