Local Excitation of Ferromagnetic Resonance and Its Spatially Resolved Detection With an Open-Ended Radio-Frequency Probe

Abstract
A local excitation of ferromagnetic resonance (FMR) and its detection were performed by using an open-ended radio frequency (RF) probe. THe RF probe is composed of a coaxial cable transmitting broadband RF waves over 10 GHz and a sharp tip attached to its end. In the reflection spectrum (S11) taken on a polycrystalline yttrium iron garnet disk, three kinds of FZMZR absorption signals were observed. Intensity of the three signals showed strong spatial dependences over the sample, demonstrating the potential of the local probe for spatially resolved FMR microscopy.Citation
