Аннотация: The automated system for measuring ferromagnetic resonance spectra in the radio frequency range has been developed for measuring magnetic characteristics of thin films. The system allows measuring the spectrum of ferromagnetic resonance at a frequency of 12 MHz with a field step of 0.01 Oe (constant or variable) and with 0.0125° anПоказать полностьюgle resolution. Automatic determination of the anisotropy field and automatic sensitivity adjustment of the measuring system allows obtaining data from permalloy thin magnetic films samples with thickness less than 50 nm. Measurements can be carried out with different directions of external magnetic fields (in the plane of the TMF sample) and with rotation of the sample in the external magnetic field. This is achieved by the independent automatic rotation of the sample and high-frequency Helmholtz coils. Processing and transmission of the received data in the digital form provides automatic processing and representation of measurement results on the PC screen. The measurement results can be used for TMF study, assessing the quality, rejection and further use in finished devices. © 2021 IEEE.
