dc.description.abstractThe magnetic properties of Pt/CoFeTaB/Ir and Ir/CoFeTaB/Pt trilayer thin films have been studied using angular- and temperature-dependent ferromagnetic resonance. This enables quantitative determination of the various contributions to the magnetic behavior, including separating, the effective Gilbert damping, inhomogeneous damping, and two-magnon-scattering contributions to the magnetic dissipation. As-deposited films show behavior consistent with significant incorporation of Ir into CoFeTaB only when the Ir layer is deposited first.

A holistic consideration of the magnetic resonance behavior can provide detailed information on the atomic-scale structure in magnetic thin-film devices.
