Abstract : The report details the chemical preparation processes for formation of three cation spinel ferrite films and garnet ferrite films. Analysis and calculation of the basic chemical solutions are included. Crystal structure and composition are verified by X-ray diffraction analysis. Magnetic properties are evaluated at X-band by cavityresonance measurements. Experimental data are included. Alcoholic solutions of ferric nitrate and other metal nitrates were combined in necessary proportions to yield stoichiometric ratios of the desired ferrites, which were then deposited on substrates. Firing the coated substrates between 900-1100C in a controlled atmosphere resulted in spinel and garnet ferrite formation. (Author)
