Abstract

The investigation of propagating spin waves is a key topic of magnetism at present. For the excitation of spin waves with short wavelengths, it was typically necessary to either use patterned transducers with sizes on the order of the desired wavelengths (striplines or point-contacts) or to generate those spin waves parametrically by a spatially uniform double-frequency microwave signal. Only recently, a new mechanism for the local excitation of spin waves has been discovered, which overcomes the lower wavelength limit given by the minimum patterning size. This method utilizes the translation of natural topological defects, namely the gyration of magnetic vortex cores to generate isotropically propagating spin waves.
