Title: X-ray diffraction and Raman scattering study of Cr-doped ZnFe{sub 2}O{sub 4} spinel ferrites

XRD and Raman scattering measurements were made on polycrystalline ZnFe{sub 2-x}Cr{sub x}O{sub 4} (x=0.0, 0.1, 0.2) spinel ferrites as prepared by solid-state reaction route. Rietveld refined X-ray diffraction pattern confirmed the formation of single-phase and are indexed in cubic structure with Fd3m space group. Slight reduction in the lattice parameter from 8.435 to 8.410 วบ, with Cr{sup 3+} ion substitution has been observed. From Raman scattering spectra, the modes of ZnFe{sub 1.9}Cr{sub 0.1}O{sub 4} and ZnFe{sub 1.8}Cr{sub 0.2}O{sub 4} are shifted towards the lower frequency side as compared to ZnFe{sub 2}O{sub 4}, this red shift is attributed to higher atomic mass of Zn (65.39 amu) as compared to Fe (55.84 amu)
