Structural, Magnetic and Dielectric Properties of Aluminum Cobalt Substituted M-type Strontium Hexaferrites

C.C. Chauhan, R.B. Jotania, C.S. Sandhu

SrCoxAlxFe(12-2x)O19 (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) hexaferrites have been synthesized using a simple heat treatment method and characterized using various instrumental techniques such as FTIR, XRD, SEM, VSM and dielectric measurements. The XRD analysis reveals the formation of mixed phases of M-type hexaferrite and α-Fe2O3. The crystallite size is found in the range of 24-46 nm. The micrographs of typical samples show porous and agglomerated grains. The values of Ms, Mr, Hc decreased with the increase of Co–Al content. The values of the dielectric constant, tangent loss, AC conductivity and dielectric modulus were studied as a function of frequency.
