The influence of hydrogenation on the magnetoresonance characteristics of nanocomposite films during synthesis is studied by the method of ferromagnetic resonance (FMR). It is shown that introduction of hydrogen into the working chamber during the synthesis of film nanogranular structures (CoFeB)mC100-m leads to a change in a resonant field, to increase of the absorption line width, to reduction of anisotropy field in the film plane.

Results are reported for the line width of the ferromagnetic resonance in pure iron whiskers. Line widths were measured at 24.5, 35, and 73 GHz and at room temperature and 4.2 °K. An unsuccessful attempt was made to detect the antiresonance at ω = γB, where γ is the spectroscopic splitting factor of the electron spins in iron.

Thin Magnetic Films

Using the scanning spectrometer of ferromagnetic resonance (FMR) the experimental dependences of the resonance field and FMR line width of thin permalloy magnetic films, which were deposited in vacuum on the substrate with an artificial texture, were obtained. The texture was produced by putting parallel grooves using a diamond cutter on glass substrates with period from 5 to 100 μm. It was found that the presence of the texture led to a considerable increase of the resonance field and FMR line width, when the external field was directed orthogonal to the grooves. On the base of a numerical micromagnetic simulation the explanation of the nature of observable in thin magnetic films effects was given.
