  • Abstract
    The ferromagnetic resonance linewidth ( Delta H) of LiTiZn ferrites is measured in a broad ranged of frequencies (up to 40 GHz) and temperatures (between 77 K and 400 K). This allows a determination of the anisotropy field (Ha) and of the first anisotropy constant (K1). The porosity contribution ( Delta Hp) does not correspond to the theory at all and an approach is presented to the porosity theory which fits present Delta Hp data. Results confirm the expected decrease of anisotropy with the double Ti-Zn substitution.
