Abstract

The paper investigates the dispersion properties of spin waves by linearizing the LLG equation, which is applied to long samples with transverse dimensions on the nanometer scale, assuming their polycrystalline structure. The obtained dispersion law generally coincides with the result of another well-known theoretical model of spin wave propagation, the Kallinikos-Slavin model. The model limitations caused by such assumptions as: absence of Hilbert damping and absence of internal anisotropy (polycrystallinity) are analyzed. Quantitative characteristics are obtained for the most common magnetic materials in practical applications, on the basis of which potential frequency ranges are identified in which the exchange interaction prevails and in which the quadratic law of spin wave dispersion is revealed. The results obtained are promising for future generations of telecommunications technologies and biochemical research due to the well-predicted properties of spin waves and the possibility of miniaturization of devices for detecting electromagnetic radiation in the gigahertz range.
