Synthesis and structural study of multiferroics in the Gd x Bi 1−x Cr 0.5 Fe 0.5 O 3 system (x=0.1, 0.2, 0.5)

Abstract

The synthesis of compounds was carring out in the system of gadolinium chromite - ferrites doped with bismuth.
The citrate-nitrate method was chosen as the synthesis method. An X-ray phase analysis was performed to study the formation
of new phases. Based on the results of x-ray phase analysis, it was determined that the obtained compounds in the chromiteferrite system are crystallized in orthorhombic syngony with the Pbnm(62) spatial group. It is showing that when nitric acid
is using as a precipitator, can be obtaining single-phase powders. In addition, the structure and parameters of elementary cells
of synthesized chromite - ferrites were determining by x-ray phase analysis. The shapes and sizes of the resulting manganite
powders determined by electron microscopy. According to the results of the scanning electron microscope, the powders of
synthesized chromite-ferrites consist of crystals from 184.3 nm to 3.02 microns
