Spinel structured ferrite materials have been explored more than the other types as bearing simplified structural analysis and also their synthesis methods. In this present report Cr2+ doped spinel structured cobalt ferrite nanopowder materials have been synthesized and characterized. For investigation of structural, morphological, and magnetic properties, analytic techniques such as powder X-ray diffraction, FT-IR, FESEM, and VSM have been employed. The phase analysis from XRD data showed the spinel structure with the lattice parameters with the range of 8.328–8.412 Å. The FESEM images show non uniform size and shape distribution of these different composition powder samples. The VSM measurement shows a decreasing saturation magnetization as the Cr2+ content increases. Whereas, the coercive force and remnant magnetization at first increase and then decrease with Cr2+ content. Keywords: Cobalt ferrite, Inverse spinel structure, XRD, Raman spectra, VSM |
