 Abstract: We present an analysis of the dynamics of isolated magnetic antivortices preformed by high frequency absorption measurements from the linear via the non-linear to the switching regime. Static magnetic bias fields are used to deflect the antivortex out of the equilibrium position and the shift of the resonance frequency of the gyrotropic eigenmode is observed. The results from the absorption measurements for highly anisotropic annihilation fields of the antivortex are compared with magneto-resistance measurements and micromagnetic simulations.
