Abstract
The purpose of the study is to assess the influence of Zn2+-Zr4+ dopant upon morphological and magnetic aspects of SrM (M-type Strontium hexaferrites). In the current investigation, a series of SrZnxZrxFe12-2xO19 (x = 0.00-0.15) were manufactured by employing the sol-gel auto-combustion technique (SGACT). The formation of the pure phase has been revealed from XRD data of strontium hexaferrites without the existence of an intermediate phase for instance alpha-Fe2O3, SrFe2O4 and SrCO3. The lattice parameter 'c' increases from 23.0601 to 23.0703 & ANGS; and cell volume increases to 692. 68 & ANGS;(3) from 691.38 & ANGS;(3) with an increment in Zn2+-Zr4+ content. With substitution, FESEM images reveal an increase in the particle as well as agglomerates size. DLS data also show an increase in size of particle from x = 0.00 (& AP;130 nm) to x = 0.15 (& AP; 500 nm). Raman spectra reveal crystals straining with an increment in Zn2+-Zr4+ content. The coercivity values (H-c) range from 5164Oe (x = 0.00) to 6210Oe (x = 0.15) as disseminated by magnetic measurements. The corresponding values of saturation magnetization (M-s) fall between 71.22 and 82.16 emu/g. The augmentation in magnetic characteristics of SrM upon doping with Zn2+-Zr4+ could be vital for permanent magnet applications.
