Effect of substitution of higher concentration of Pb~(2+) ion on structural and magnetic properties of LaMnO_3 at A-site

摘要

The (La1-xPbx)MnO3where x = 0.3-0.5 solid solutions were prepared using solid state reaction route. The X-ray diffraction (XRD) data reveals the single phase formation. The microstructures shows that grain size as well compactness of grains increases with increasing Pb2+ content. However density of the samples also increases with incraesing x. The magnetic data shows the ferromagnetic behavoir of the solid solutions as x increases from 0.3 to 0.5.
