Influence of Mn substitution on structural, electrical, and magnetic properties of Li0.5Fe2.5-xO4

The influence of Mn inclusion on the structural, electrical, and magnetic parameters of Li0.5Fe2.5O4 wad analyzed. To procure nanoparticles of all the samples, a simple sol–gel self-combustion method was employed. In-depth, refinement of structural patterns reflects the ordered spinel phase (P4332) starts to demolish, and mixed-phase formation takes place with the replacement of Fe with Mn ions. FTIR gives similar findings, i.e., change of space group from P4332 to mixed phase with P4332 and Fd-3 m as the major characteristic absorptions and its shoulder bands start to smear out with the inclusion of Mn. FE-SEM images reflect that morphological tuning occurs through clustered nanoparticles’ agglomeration. The declining of electrical parameters dielectric constant, and loss tangent, indicates that electron hopping gets deterred through the inclusion of Mn. DC resistivity and activation energy are enhanced with the inclusion of Mn. The magnetic parameters also decline with Mn inclusion in the lithium ferrite lattice.
