Abstract

The hexagonal ferrites LaxBa1-xFe12-xZnxO19 were prepared by oxalate eopreci-pitation method. The ferrites with magnet oplumbite structure were found to be formed for xf and the magnetic crystal anisotropy constant k decreases with increasing x. M?ssbauer spectra have revealed that Zn2+ ion tends to occupy 4f2 site.
