Abstract
- We have synthesized a series of LuMn1-xFexO3 (0⩽x⩽0.2) samples and study the effect of Fe-doping on their magnetic and dielectric properties. The magnetic characterization indicates that with increasing Fe-content up to 0.2, the antiferromagnetic (AFM) transition temperature increases from 90 to 105 K. A corresponding shift in the peak-positions of specific heat and dielectric anomaly is observed, indicating a strong correlation between the magnetic ordering and the electric polarization. Further analysis suggests that the rising of AFM transition temperature with increasing Fe-content should be from the structural origin, in which the strength of AFM interaction as well as the electrical polarization is dependent on the in-plane lattice parameters.
