In preparing nanoparticles sample containing yttrium iron garnet doped with Manganese and Gadolinium. I observed that the main phase in xrd peaks decrease with the increase of Gd and Mn. How can we justify this phenomenon?
The intensity of the peak, or more precisely the area under the peak, is proportional to the content of the crystalline microphase. If you increase the content of new microphases, then the content of those already present decreases.
