Investigation of structural, morphological, and transport properties of a multifunctional Li-ferrite compound

Abstract

Oxide lithium-manganese ferrite spinel representation, with stoichiometry LiMn0.5Fe2O4, in the (110) plane.

Research on the physical properties of LiMn0.5Fe2O4 spinel ferrites by the combination of optical, magnetic, and dielectric behaviors

“…All the structural parameters deduced from the Rietveld analysis were mentioned in our previous work. 30 …”

“…The average estimated diameter of the grain was relatively large, of the order of 2.48 μm, as detailed in our preceding paper. 30 …”

“…The factor group process foretells the subsequent vibrational modes in spinel by the following: Γ = A 1g (R) + E g (R) + 3F 2g (R) where (R) represents Raman active vibrational modes. LiMn 0.5 Fe 2 O 4 has a cubic structure belonging to the Fd 3̄ m space group 30 and according to group theory, 5 Raman active modes (A 1g + E g + 3F 2g ), acquired under ambient conditions, are recognized for this structure space group. They are dependent on the motion of both A and B site cations and oxygen ions.…”

“…The large size of particles D SEM deduced from scanning emission microscopy ( D SEM is about 2.48 μm (ref. 30 )) indicates great potential for developing and improving superparamagnetic nanoparticles from metal oxide material, especially spinel ferrite. 48 …”

“…The XRD diffraction peaks correspond to those of the cubic LiMn 0.5 Fe 2 O 4 spinel. 30 Our previous results 30 revealed that the compound could be a multifunctional material with the potential to drive technological innovation forward. The electrical properties of the compound have proven that it can be used in various applications such as optoelectronics, photodetectors, photovoltaics, and full-cell low temperature-co-fired ceramics (LTCCs).…”
