    Abstract: In this paper it is study a problem of multigrid schemes in two space dimensions and differential operator formula of Laplace and Lagrang for numerical tests, including a composition parameters of microstructures obtained by the DDS method. This technological possibilities of directed crystallization are broad and make it possible to manufacture ca... Show More

    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 magnet... Show More
