(a)-(b) Out-of-plane angular dependent resonance fields for sample Ta(0.8)/Co20Fe80(0.8)/MgO(0.8)/Ta(1.0) (in nm) in the as-deposited and 240°C annealed states. Hollow circles and solid lines represent experimental data and theoretical fitting of . Inset: typical FMR differential absorption spectra where the resonance field and peal-to-peak linewidth are defined.
