Ni ferrite crystalline material is synthesized using a sol-gel method at two different temperatures. The vibrational and stretching modes, crystalline phase, size distribution and morphology of the products are investigated via Raman back-scattering and Fourier transform infrared (FTIR) spectroscopy, XRD and FESEM, respectively. Vibrational modes of spinel ferrite are observed at Raman and FTIR spectra. Group theory phonon analysis reveals five Raman active modes for the molecular system. However, in the present investigation, four Raman modes are identified in the inelastic Stokes region of the recorded Raman scattering spectra. Also, the results of the present study reveals that the sizes of the synthesized particles were increased and crystalline structures were completed by increasing the temperature.
