Description
Results on magnetic studies of Ba0.5Sr0.5Fe12-2x(ZnTi)xO19 and Ba0.75Ca0.25Fe12-2x(ZnTi)xO19, where x = 0.2 to 0.6, ferromagnetic powders prepared by mechanical alloying are discussed. The structural and magnetic properties of the resulting powders were analyzed by thermo-magnetic analysis, X-ray diffraction, scanning electron microscopy, Moessbauer spectroscopy and magnetic measurements. Curie temperature, Tc decreased dramatically (drop ∼ 39%) for BaCa samples, whilst for BaSr samples remained almost without change (diminution ∼ 2%) at x ≤ 0.2. SEM studies showed that all the particles present nearly hexagonal platelet shape.
