Low-dimensional molecular magnets attract nowadays an increasing interest since they are candidates for future devices with improved performance and enhanced functionality. We focus our attention on multidecker vanadium-benzene (VBz) molecules which are one-dimensional ferromagnets and can work as highly effective spin filters when they are coupled to the spin-polarized electrodes. Here, we show our generalization of the non-equilibrium Green's function method for non-collinear systems in order to describe and analyse the transport through the VBz clusters suspended between electrodes with antiparallel magnetization. We have found that non-collinear description redistribute the magnetic moments on the vanadium atoms in comparison to the collinear calculations, what affects to the transmission across the molecule.
