Indium-substituted yttrium iron garnet samples, Y3Fe5 xInxO12 (x ¼ 0e0.7, step 0.1), were prepared using a citrate solgel method. Synchrotron X-ray diffraction (SXRD) measurements combined with the Rietveld refinement technique were used to investigate the crystallization, structure parameters and...
