  We have measured the angular dependence of ferromagnetic resonance (FMR)
spectra for Fibonacci-distorted, Kagome artificial spin ice (ASI). The number
of strong modes in the FMR spectra depend on the orientation of the applied DC
magnetic field. In addition, discontinuities observed in the FMR
field-frequency dispersion curves also depend on DC field orientation, and
signal a multi-step DC magnetization reversal, which is caused by the reduced
energy degeneracy of Fibonacci-distorted vertices. The results suggest the
orientation of applied magnetic field and severity of Fibonacci distortion
constitute control variables for FMR modes and multi-step reversal in future
magnonic devices and magnetic switching systems.
