VILLAQUIRAN RAIGOZA, Claudia Fernanda; MEDINA SOLARTE, Christian Felipe  e  TIRADO-MEJIA, Liliana. Effect of cobalt-incorporation on the properties of Sr_xBa_1-xNb₂O₆ system. Ing. Desarro. [online]. 2015, vol.33, n.2, pp.281-300. ISSN 0122-3461.  https://doi.org/10.14482/inde.33.2.6341.

Results on the synthesis process of nanometric ceramic powders of the Sr_xBa_1-xNb₂O₆ compound (SBN) for two values of x (0.50 and 0.61). SBN exhibits ferroelectricity in the composition range 0.25<x<0.75. It belongs to the family of tetragonal tungsten bronze structured ferroelectrics. Reaction combustion method was used in order to obtain fine ceramic and single-phase powders using temperature as low as 900° C. Addition of cobalt generated ferromagnetic behaviour reflected in magnetic hysteresis curves obtained at room temperature.

Palavras-chave : combustion reaction; ferroelectric; ferromagnetic.
