An investigation into the multiferroic properties of LuFe₂O₄ based systems under the influence of electron-hole doping

Hexagonal LuFe₂O₄ and LuFeO₃ based systems have recently come under the limelight of scientific interest and curiosity following the observation of near room temperature multiferroic and magnetoelectric phenomena in their superlattices.¹ The origin of these phenomena lies within the hole-doped LuFe₂O₄ layer^2,3, which is contingent on various microscopic factors, such as geometric frustration, spin-orbit coupling and charge ordering. These factors vary in degrees with the variation in the doping concentration in the system and this in turn is expected to contribute to the manifestation of interesting quantum phenomena. We, therefore, have studied the bulk LuFe₂O₄ under the influence of electron-hole doping to gain further insight into the interesting quantum phenomena in these systems.
