Abstract
Doped ferrites were fabricated by usual ceramic sintering method. The ferrite powders possess hexagonal shape and are well separated from one another. X-ray diffraction (XRD), scanning electron microscope (SEM), vector network analyzer and a.c. susceptometer were used to analyze structures, electromagnetic and microwave absorption properties of prepared ferrites. The results showed that the magnetoplumbite structures for all the samples have been formed. Also the present investigation demonstrates that microwave absorber using BaFe9Mn1.5Ti1.5O19/polyvinylchloride can be fabricated for the applications over 15 GHz, with reflection loss more than −25 dB for specific frequencies, by controlling the molar ratio of the substituted ions.
