Synthesis, dielectric and magnetic properties of Mn-Ge substituted Co2Y hexaferrites

The substituted strontium Y-type hexaferrites Sr2Co2GexMnxFe12−2xO22 (X = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5) was synthesized by sol–gel auto-combustion method. The crystal structures of the present materials were identified using X-ray diffraction analysis. The XRD patterns of the prepared samples poi...

description The substituted strontium Y-type hexaferrites Sr2Co2GexMnxFe12−2xO22 (X = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5) was synthesized by sol–gel auto-combustion method. The crystal structures of the present materials were identified using X-ray diffraction analysis. The XRD patterns of the prepared samples pointed out the successful formation of Y-type hexagonal phase. The dielectric and magnetic properties have been studied for Ge-Mn substituted Y-type hexaferrites. The results showed that the dielectric parameters decrease with increasing frequencies. The values of magnetic parameters such as saturation magnetization, remanent magnetization and magnetic moment were found to decrease which are attributed to the weakening of super-exchange interactions. The values of Squareness ratio are found to be 0.48–0.56, which shows that the fabricated materials are multi domain. With decreasing dielectric parameters and increasing coercivity support these investigated samples have appealing applications in micro-wave devices, and Multilayer chip inductors. Keywords: XRD, EDX, Dielectric loss, Coercivity, Multilayer chip inductors
