Abstract :
W-type Pb-hexaferrites were prepared by standard ceramic methods. The lattice constants found by refinement were a=0.59140±0.00006 nm and c=3.29209±0.00041 nm. The X-ray density of a typical composition PbZn1.9Fe15.3O25.8 was ρ=5.32 g/cm3 and the Vickers microhardness value h v=6 kN/mm2. A plot of the saturation magnetization versus temperature is given. The extrapolated value of the saturation magnetization (H→∞, T→0) was σs=108 emu×g-1, and the Curie temperature was Tc=600±20 K
