The main theme of this work was to synthesize and investigate the microwave absorbing material (MAM). For this purpose, a rare earth Pr3+ and transition element Cu2+ substituted series of X-type hexaferrites Sr2-xPrxCo2Fe28-yCuyO46 with concentration (x = 0, 0.02, 0.06, 0.1 and y = 0, 0.1, 0.3, 0.5) was synthesized by adopting the sol gel method. The thermal analysis was carried out to know the sintering temperature at which the single x-type phase can be attained. The XRD patterns show the single phase for all the samples. The Pr-Cu substitution in pure x-hexaferrites changed the structural parameters. The nano-particle size of the material was confirmed from the TEM analysis. The HRTEM image and SAD pattern indicates that the material is well crystallized. The FTIR analysis also confirms the single phase for prepared materials. The increment in dielectric properties with Pr-Cu substitution was observed. The magnetic properties of the material were enhanced with additives. The material exhibited the minimum value of reflection loss (microwave absorption) at higher frequencies which makes this material useful to act as microwave absorbing material (MAM) for super high frequency (SHF) devices.
