Effect of cobalt-incorporation on the properties of SrxBa1-xNb2O6 system

Abstract

Results on the synthesis process of nanometric ceramic powders of the

SrxBa1-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 900º C. Addition of

cobalt generated ferromagnetic behaviour reflected in magnetic hysteresis

curves obtained at room temperature.
