Abstract
A structural and magnetic study of the system X(SrFe12O19) + (1-X) (BiFeO3) with X=0, 0.20, 0.40, 0.50, 0.60, 0.80 and 1.0 is presented in this work. The individual phases were obtained by the Sol-Gel method. The powders were mixed by mechanical grinding, then pressed and sintered. Experimental techniques of X-ray diffraction and vibrational magnetometry were used for the characterization of the samples and the Hanawalt method and the Match! Phase Identification from Powder Diffraction were used for the qualitative determination of the phases present in each sample. Rietveld's analysis was carried out with the FullProf Suite-2008 program. The structural results obtained show slight variations of the crystal lattice parameters for both phases and the coexistence of both phases in each sample. The magnetic characterization shows a linear increase of the saturation magnetization, the remanent magnetization and the magnetic anisotropy constant K1, as a function of the concentration of the BiFeO3 and SrFe12O19 phases. A satisfactory congruence is observed between the theoretical predictions and the experimental measurements, an indication that the magnetic parameters reported are due to the superposition, in each compound, of their individual values. Both the XRD pattern and the structural and magnetic characterization show that the two phases coexist individually in the matrix and have a good chemical compatibility between them.
