摘      要：We investigated the angle-dependent spin wave spectra of permalloy ring arrays with the fixed outer diameter and various inner diameters by ferromagnetic resonance spectroscopy and micromagnetic *** the field is obliquely applied to the ring,local resonance mode can be observed in different parts of the *** the resonance mode will change to perpendicular spin standing waves if the magnetic field is applied along the perpendicular *** simulation results demonstrated this evolution and implied more resonance modes that maybe *** the mathematical fitting results based on the Kittel equation further proved the existence of local resonance mode.
