| Popis: | A series of Ni0.6-x/2Zn0.4-x/2SnxFe2O4 (x = 0.0, 0.05, 0.1, 0.15, 0.2 and 0.3) (NZSFO) ferrite composites have been synthesized from nano powders using standard solid state reaction technique. The spinel cubic structure of the investigated samples has been observed by the X-ray diffraction (XRD). The magnetic properties such as saturation magnetization (Ms), remanent magnetization (Mr), coercive field (Hc) and Bohr magneton (B) are calculated from the hysteresis loops. The value of Ms is found to decrease with increasing Sn content in the samples. This change has been successfully explained by the variation of A-B interaction strength due to Sn substitution in different sites. The compositional stability and quality of the prepared ferrite composites have also been endorsed by the fairly constant initial permeability (/) over a wide range of frequency region. The decreasing trend of / with increasing Sn content has been observed. Curie temperature (TC) has found to increase with the increase in Sn content. Wide spread frequency utility zone indicates that the NZSFO can be considered as a good candidate for use in broadband pulse transformer and wide band read-write heads for video recording. The abnormal behavior for x = 0.05 has been explained with existing theory. Comment: Submitted to Chinese Physics B (2017), 14 pages |
