Abstract

M-type hexagonal ferrites with composition SrFe12-yMg19-y/2 have been prepared by the co-precipitation method. The X-ray powder diffraction was employ to investigate their nanostructure constants. The X-ray data were analyzed using different softwares. The average values of lattice constants (a) and (c) are found in the range (5.867– 5.876) A and (22.918– 22.977) A respectively and the average crystallite size is found in the range 71 – 93 nm. SrFe11.5Mg0.518.5 sample is the critical concentration where it has the minimum value of (a) lattice prameter, the minimum value of crystallite size and the maximum value of lattice strain.
