We have synthesized three different hexagonal Magnetoplumbite (M) types of ferrites by standard ceramic method at a high temperature of 1403 K. These ferrites are namely Lanthanum La substituted for Fe in Barium (BaLa0.2Fe11.8O19), Strontium (SrLaFe11O19)), Calcium (CaLa0.5Fe11.5O19) ferrites. Their characterization is performed by using X-ray diffraction studies (XRD), Scanning electron microscopy (SEM) and Magnetic Studies By Quincks method. The XRD studies of te sample are very interesting. Lanthanum substitution Sr and Ca ferrites the 2 and d values are nearly same for the maximum intense planes of 1 and 2 order diffraction peaks at (107) and (114) planes, however lanthanum substitution for Ba gets reversed for the same intense planes. These three ferrites crystallize into hexagonal magnetoplumbite structure with lattice parameters, for Ba: a = 5.87 Å, c = 22.17 Å for Sr; a= 5.82 Å, c= 22.10 Å, Ca: a= 5.81 Å, c= 21.87 Å. The SEM studies for Ba and Sr indicate the morphology of the samples to be regular equal in size and are hexagonal in shape, however the SEM micrographs of Ca ferrite are irregular in shape. The EDX studies shows the exact presence of pure elements Sr, La, Fe and O present in the sample.
