In spintronics thin films with out of plane magnetization are highly desirable for, e.g., electrodes in tunnelling cells or substrates for molecular magnets. The goal of our work is to be able to define desired film properties and to tailor the thin films correspondingly. For our approach we have chosen [CoPd]X as hard magnetic and [CoAu]X as soft magnetic multilayers. Mixing those multilayer systems gives the possibility to design the material properties. The multilayer systems have been prepared using sputter deposition techniques and the resulting thin films have been investigated with AGM, STM and MFM. The measurements give an insight into the structural and magnetic properties of the tailored samples and improve the ability to property design.
