perpendicular nanomagnetic logic (pNML) applications. Starting from single and bilayer stacks, the material system is explored for maximum Co thicknesses while preserving perpendicular magnetic anisotropy (PMA) as well as single-domain behavior for micrometer-sized structures. Results for single trilayers show significantly reduced saturation magnetizations when compared to Pt\Co\Pt. Anisotropy measurements reveal a comparable volume component together with substantially reduced surface contributions. The subsequent analysis of [Co1.22\Pt1.45\WX]2 bilayer stacks indicates the emergence of weak interlayer coupling superposed by anisotropy differences, for Tungsten thicknesses , not exceeding the low mT range. The impact of local anisotropy engineering on micro-magnetic test structures by means of ion beam irradiation for different stack compositions is investigated, targeting low nucleation fields and shaping hysteresis behaviors for single step switching. First operational dipole-coupled inverter structures based on a Pt\Co\Heavy-Metal system are demonstrated achieving clocking fields down to 50mT.     «
