XRD patterns for (A) BaFe0.6Co0.3Nb0.1O3-x and (B) BaCo0.7Yb0.2Bi0.1O3-x at 25oC.
the data is in XRD "raw" format

The crystal structure of samples was investigated by powder x-ray diffraction (XRD). 
XRD patterns (room temperature and high temperature) were collected with a D8 ADVANCE (Bruker) diffractometer with Cu Ka radiation. 
XRD patterns were collected in the temperature 25oC 


Samples of BaFe0.6Co0.3Nb0.1O3-x (BFCN) and BaCo0.7Yb0.2Bi0.1O3-x (BCYB) were prepared via the conventional solid-state reaction method. 
Analytical-grade powders BaCO3, Fe2O3, Co3O4, Nb2O5, Yb2O3 and Bi2O3, (commercially available) were initially mixed with a mortar and pestle; 
according to the molar ratios of Ba:Fe:Co:Nb = 1:0.6:0.3:0.1 and Ba:Co:Yb:Bi = 1:0.7:0.2:0.1. 
The obtained mixtures were heated first at 950 then at 1,050oC (BFCN) and 1,100oC (BCYB) for 12 h.
