ABSTRACT

In this study, SrFe12O19 hexaferrites is synthesized by citrate sol-gel auto-combustion route. The standard analytical techniques such as X-ray Diffraction analysis (XRD), Field Effect Scanning Electron Microscopy (FE-SEM), Energy-Dispersive Spectroscopy (EDS), Fourier Transformer Infrared (FT-IR) Spectroscopy, Raman spectroscopy and magnetic studies (VSM) are applied to study the characteristics of the sample prepared. The X-ray diffraction patterns are used to analyse the structural properties of the sample. The information about the particle formation and size are obtained using scanning electron microscope (SEM). An energy-dispersive x-ray analysis tool (EDX) provides the elemental composition of the nano-particle. The Fourier transform infrared (FT-IR) spectra revealed about the functional group bonds between metal and oxygen (M–O). The vibrating sample magnetometer (VSM) technique, which is recorded at room temperature, revealed the magnetic properties of the sample with the hysteresis loops showing its magnetic behaviour.
