We report on novel interface-related ferromagnetic resonance behavior in Fe/FeRh ordered alloy heterostructures. A Au/Fe/Rh/FeRh heterostructure shows a single ferromagnetic resonance line, while a Au/Fe/FeRh is found to show two distinct ferromagnetic resonance lines, which we attribute to the exchange coupling at the Fe/FeRh interface. We will discuss the origin of the anomalous behavior in more detail.
