Abstract
Polycrystalline ferrites with the formula unit SrAl0.2Fe11.8O19 have been investigated. A series of samples with uniaxial texture and various grain sizes has been obtained. The influence of the microstructure on the internal anisotropy field Ha and the resonance linewidth ΔH have been studied in the 50 to 70 GHz frequency range.
