Аннотация: Abstract: The design of inspection probes for a scanning ferromagnetic resonance spectrometer, which are designed for recording the absorption spectra of electromagnetic energy by local areas of thin magnetic films, is described. The degree of locality is determined by the diameter of the measuring hole of the probe in the range of 0.1–1.0 mm. The sensitivity of the device is significantly increased due to the miniaturization of the heterogeneous measuring resonator and its comparatively high Q factor. A set of replaceable probes makes it possible to cover the frequency range of 0.1–6.0 GHz, the signal-to-noise ratio for a probe with a hole diameter of 0.8 mm, which was measured on a permalloy film with a thickness of 5 nm, is at least 20 dB. © 2021, Pleiades Publishing, Ltd.
