Abstract
Adjacent layers of magnetically hard and soft materials are of both fundamental and technological importance, yet systematic experimental studies of how to control the interlayer exchange coupling (IEC), and how the IEC affects the magnetization dynamics in each layer, have been limited. In this study, broadband ferromagnetic resonance up to high temperatures is used to study IEC in a system with a hard Fe-Pt layer and a soft Fe-Co layer. The IEC of the soft layer strongly depends on the choice of soft material, its thickness, and temperature.
