In this work, pure and doped with Al (Aluminum) strontium hexaferrite (SrFe12-xAlxO19) were fabricated by solid state reaction method. The Al concentration (x) for the fabricated samples was varied from x=0.0 to x=0.6. Structural and magnetic properties of the fabricated samples were investigated. Analyses of XRD data showed that all samples of high quality, since the measured XRD patterns found to match the standard pattern for single phase of SrFe12O19. The lattice constants a and c were calculated. It was found that the replacement of Fe3+ with Al3+ ions in hexagonal strontium ferrite led to a negligible changes in lattice constant a, whereas the hexagonal lattice constant c found to decrease with increasing the substitution amount of Al. The crystallite size was also determined using the XRD data. It has been found that that Al3+ substitution for Fe3+ does not appreciably disturb the crystallinity of SrFe12-xAlxO19, since the crystallite size for all samples ranged from 83 – 72 nm. The magnetic data showed that doping of strontium with Al leads to a small decrease in saturation magnetization. Also it has been found that the doping of strontium ferrite with Al leads to an increase in the coercivity as a result of increasing of the anisotropy field.
