Spintronic multilayer devices are employed ubiquitously in modern magnetic data storage and sensor technology. Tremendous efforts were made to further improve these devices; however, the conventional RKKY coupling approach imposes fundamental limitations on the tunability of the magneto-electronic response.
In this contribution we describe a novel class of layered materials with magneto-electronic properties that can be almost arbitrarily tailored. A recently developed thin-film deposition technique, based on oblique incidence deposition, uniquely allows us to prepare multilayers with custom-designed magnetic properties for the first time [1]. Sample systems are characterized via magneto-optical Kerr and magneto-resistive measurements as well as with nuclear resonant reflectometry of synchrotron radiation [2].
