The optimum geometries and magnetic properties of small binary V nSim clusters are studied using Density Functional Theory. Our results reveal an enhancement in the magnetic moment at V atoms respect to the atomic magnetic moments, and the magnetic moments at Si atoms take a significative values. The magnetic order into the clusters depends of the chemical composition and of the geometrical arrangement of the clusters, for structures with n m = 4 the magnetic order is antiferromagnetic-like.
