Abstract:

This research article reveals the effect of Dy+3 substitution on ß-ferrites KFe11-xDyxO17 with composition (x=0.00, 0.25, 0.50, 0.75 and 1.0). The samples were synthesized by sol-gel autocombustion method, sintered at 950oC temperature. The XRD patterns confirmed the single phase of the synthesized samples. The crystallite size varied in the range of 21.49 nm to 25.24 nm for all samples. The polarization verses electric field (P-E) loops indicated the loosy behavior in all samples. The lossy behavior of the samples was seemed to be increased up to x=0.5 and then decreased. The theoretical expression was used to fit an upper branch of P-E loops. FT-IR spectra showed absorption bands at different wavenumbers due to M-O-M stretching vibrations, H-O-H stretching, and C-O-C stretching vibrations, which also confirmed the formation of the singlephase in the samples. Electrochemical measurements of synthesized nano ferrites were carried out by using cyclic voltammetry in a 3.0 M KOH solution. Electrochemical impedance spectroscopy (EIS) has been described by Nyquist plots.
