Abstract
Ferromagnetic antiresonance (FMAR) transmission measurements at 24 GHz, and at temperatures between 20 °C and 364 °C, are reported for polycrystalline nickel foil 20 µm thick. The results can be described by the usual equation of motion for the magnetization and using a Landau–Lifshitz damping parameter of 2.45 ± 0.1 × 108 s−1 and a g factor of 2.187 ± 0.005, both temperature independent. The temperature independence of the damping was confirmed by measurements of the maximum transmission amplitude at FMAR as a function of temperature. The data were corrected for magnetostrictive effects in order to obtain the g factor and magnetization.
