| Popis: | Rare-earth-doped ferrite nanomaterials are known to show remarkable variation in structural, magnetic, and electrical behavior compared to their un-doped counterparts. In this report, low-temperature synthesis of Gd+3-doped manganese ferrite with composition MnFe2−xGdxO4 (x = 0.02, 0.04, 0.06, 0.08) has been represented. This report includes structural investigations done using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) and morphological analysis done through scanning electron microscopy (SEM). The compositional analysis was done through energy dispersive X-ray spectroscopy EDS. The variation of electrical properties like DC resistivity ‘ρ’, mobility ‘μ’, and dielectric constant ‘e’ as a function of temperature was also investigated and was seen to depend on rare earth concentration in the ferrite structure. |
