Abstract

AbstractWe demonstrate a scanning microwave near‐field probe based on a slit aperture that is capable of performing spatially‐resolved magnetic resonance measurements in the frequency range of 3–90 GHz. We demonstrate local electron spin resonance (ESR), ferromagnetic resonance (FMR), and spin‐wave resonance (SWR) studies on model materials. The probe can serve as a local contactless heater as well. We demonstrate also a further application, a dual microwave/optical near‐field probe that can be useful in contactless measurements of photoconductivity and fluorescence under microwave irradiation.
