“…The FMR properties of Fe 1-x Co x Fe 2 O 4 nanoparticles were studied in the frequency band f   8…40 GHz at the temperature T  300 K. Each MNP sample enclosed in a spherical dielectric container was placed inside a tunable rectangular microwave cavity resonator [7,14] inserted between the poles of the electromagnet and connected to the spectrometer [10,15]. The MNP samples were examined in scanning mode by applying an external magnetic fi eld in the range H  0…10 kOe.…”

“…Microwave power absorption can be measured as a function of the radiation frequency (ω) with the DC magnetic field (H DC ) constant; or as a function of H DC under a fixed microwave frequency. The first kind of measurement, broadband FMR [16,17], requires a microstrip line or coplanar waveguide setting for transporting the microwave field. In this setup, the sample is mounted onto the waveguide, and the reflected and absorbed waves are analyzed while the system is kept under a fixed DC magnetic field H DC .…”

“…However, with regard to micro-scale characterization, methods that use magneto-optical phenomena find their application [ 6 , 7 ]. The latter group also includes methods based on resonance phenomena, which in the case of magnetic materials specifically refers to ferromagnetic resonance FMR [ 2 , 8 , 9 , 10 , 11 , 12 , 13 ].…”

“…The FMR technique was introduced in the middle of the 20th century and is well known. During the standard FMR experiment, a sample is placed inside a microwave resonator, and a system is under the operation of an excitation wave at a fixed high-frequency [ 2 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. By sweeping of an external bias DC field, perpendicular to the excitation one, the resonance conditions are being found.…”
