Antiferromagnets (AFs), and in particular synthetic antiferromagnets (SAFs), are gaining increasing interest due to their wide variety of useful properties at the micro and nanoscale. Despite of their macroscopically vanishing remanent magnetic moment and therefore high stability with respect to external magnetic field, AFs and SAFs may also provide other unique static magnetic states as well as promising characteristics for dynamic applications, such as high domain wall velocities and excitation frequencies reaching into the THz regime.
Although the static magnetic properties of atomic AFs are intrinsically predefined by their crystal structure, SAFs allow for much more freedom, due to their much larger degree of tunability. Furthermore, SAFs grant easy access to magnetic textures and even allow to manipulate them, for example via the surface spin flop (SSF), towards the desired behavior. We will report on the control of SSF mediated vertical AF domain walls, which may prove to be a promising platform for magnetization dynamics and thus are an interesting candidate for future applications, such as re-programmable spin wave guides.
