PNR determination of magnetic interface states and exchange coupling in hybrid anisotropy thin films

The atomic interfaces between ferromagnetically ordered thin films with perpendicular anisotropy and either films with magnetically ordered in-plane anisotropy or a non-magnetic metal are responsible for nearly all the exciting physics leading to potential devices in areas as diverse as broadband THz generation, DMi and Skyrmions, Spin Hall effects, Spin torque/Vortex oscillators (STO) and data storage. Understanding the magnetic structure of these atomically engineered interfaces as a function of depth is a key element in optimizing layer structures and developing the underlying physical insight necessary for exploitation.
