2020 7th International Congress on energy fluxes and radiation effects (EFRE 2020), Tomsk, Russia, September 14 – 26, 2020 : proceedings P. 1334-1337Abstract: Abstract—The hexaferrites of the Co2-xZnxW system have a number of outstanding properties among other hexaferrites. This makes them promising both for obtaining new physical data and for practical use. In this paper, we analyze the concentration and temperature dependences of the resonance frequencies of natural ferromagnetic resonance and the damping constant in the equation of motion of the magnetization vector of these materials in the vicinity of spin-reorientation phase transitions. It is shown that these hexaferrites can find practical application in the entire microwave frequency range.
