Influence of V2O5 Addition on the Magnetic Properties of Li-Zn Ferrites
M. Samir Ullah,Sm. Rubayatul Islam,M. Atikul Islam,M. Hassan,M. Firoz Uddin,M. Mizanur Rahman 한국자기학회 2023 Journal of Magnetics Vol.28 No.1
The structural property, bulk density and porosity of V2O5 (0.0, 0.4, 0.8 and 1.2 wt.%) added Li-Zn ferrites are observed along with the surface morphology. The samples have been prepared by the solid-state reaction technique and sintered at 1050 oC. The X-ray diffraction patterns of the prepared samples have shown the single phase cubic spinel structure. A microstructural study demonstrates that the grain size increases up to 0.8 wt.% V2O5 and slightly decreased thereafter for 1.2 wt.% V2O5 addition. The saturation magnetization value increases from 44.0 to 50.3 emu/g as the V2O5 content increases up to 0.8 wt.%. The decrease of magnetization for 1.2 wt.% V2O5 content is apparent and it is found to be 47.3 emu/g. This may be related to the dilution effect with the excess of non-magnetic V2O5. It is also observed that the value of initial permeability increases up to 0.8 wt.% V2O5.
