Effect of Fe doping on the structural, dielectric, and magnetic properties of Li V(1-X) Fex O3 (x=0,0.1,0.3) ceramics

The present work is on the structural, dielectric and magnetic properties of LiV((1-x))Fex O-3 (x = 0,0.1,0.3) ceramics samples. The Rietveld refinement of XRD pattern reveal that the crystal structure of all samples are monoclinic with space group C2/c. Structural studies also suggests that Li site disorder increases with increase in Fe doping concentration, leads to the formation of minor phase of Li3VO4. The Raman spectra shows red shift with increase in Fe content to parent LiVO3. The dielectric constant at low-frequency increase with Fe doping content and undulates at high frequency range due to grain boundary effect. The magnetic properties of LiVO3 has been significantly changed with Fe doping. The diamagnetic behavior of parent material changes to weak ferromagnetic nature when doping with Fe.
