Abstract
Mössbauer and magnetic measurements have been carried out both on single crystals and polycrystalline samples of BaZn2Fe16O27 (Zn2-W) hexagonal ferrite. The saturation magnetization at 0 K and at room temperature turns out to be very high, that is, 123 and 79 Gauss·cm3/g, respectively. The results have been interpreted by assuming a local reversal or a weakening of the Fe3+ magnetic moments due to the perturbing action of Zn2+ ions. The magnetic anisotropy is confirmed to be uniaxial with an anisotropy field at room temperature of 12.500 Oe.
