SYNTHESIS, STRUCTURAL AND OPTICAL PROPERTIES OF Zn-SUBSTITUTED Co W-FERRITES BY COPRECIPITATION METHOD

A series W-type BaMe2Fe16O27 ferrites withcomposition BaZnxCo1-xFe16O27(x ═ 0.0, 0.1, 0.2, 0.3, 0.4 &0.5) were manufactured by co-precipitation method sintering at 1100°C for 8 h. XRD, FTIR, SEM, UV-vis and I-V techniques were applied to investigate structural, optical, morphological and electrical properties respectively. Crystallite size was observed in the range of (37.58 nm- 54.75 nm) revealed by XRD and was confirmed by SEM analysis. IR exposed the existence of metal oxides (M -O). Optical band gap was in (3.0 eV- 5.2 eV) range which proved the trend of DC resistivity in increasing trend. Activation energy discovered the conversion of ferrimagnetism to paramagnetism characteristics confirming the W-type materials are highly suitable for novel application.
