We report on a frequency-specific linewidth broadening of the ferromagnetic resonance (FMR) mode
of a NiFe free layer within a magnetic multilayer stack. The FMR studies reveal a significant
broadening of the FMR linewidth of the free layer at frequencies where this resonance is degenerate
with FMR modes stemming from other layers within the multilayer stack. By pinning part of the
magnetic multilayer to an antiferromagnet, we tailor a ferromagnetic linewidth behavior that is
anisotropic for a specific frequency.
