Here we explore new spin textured interfaces by using as a substrate non-conventional magnetic surface- confined alloys, which contains rare earths (RE) atoms and Au. The broad number of possible RE atoms used for the preparation of such alloys provides an attractive platform to optimize and tune magnetic metal-organic interfaces with many different spin textures. We focus on the growth of CuPc on different 2D surface compounds like GdAu2, HoAu2, and the paramagnetic YbAu2. For the study of the electronic properties we use X-ray and angle resolved photoemission spectroscopy, while the magnetic properties of the systems were investigated by X-ray magnetic circular dichroism. We observe similar electronic interaction of CuPc on these surfaces, with variation depending on the valence of the RE atom. From the magnetic point the different RE atom of the substrate induce different magnetic interactions with the the CuPc molecule.
