METHOD FOR PRODUCING MULTIFERROICS BASED ON FERROMAGNETIC GLASS MATRIX Russian patent published in 2021 - IPC C03C10/02 C04B35/465 C04B35/624 B82Y40/00 

FIELD: multiferroic production.

SUBSTANCE: invention relates to the technology of producing oxide glassy composites –multiferroic, combining ferromagnetic and electrical characteristics. The glass-crystal composite is obtained by creating a porous glass matrix of iron-containing silicate glass, in the pore space of which the ferroelectric phase Ba_0.75Sr_0.25TiO₃ is introduced. An aqueous solution of titanyl nitrate is obtained, aqueous solutions of barium nitrate or barium acetate and strontium nitrate are added, and the solution is mixed with glycine in a stoichiometric ratio to obtain a complex oxide Ba_0.75Sr_0.25TiO₃. A plate of porous ferromagnetic glass is placed in the resulting solution. The impregnated sample is extracted, dried, and subjected to heat treatment at a temperature of 550-700ºC with an exposure of 0.5-3 hours.

EFFECT: analysis of the magnetic characteristics of the obtained glass-ceramic composites showed a significant increase in the magnetization of the formed composite material in comparison with the original glass matrix.
