Abstract
We studied the effect of Fe doping on structural, magnetic, and dielectric properties of hexagonal ErMnO3 system. For 50% doping of Fe on Mn site in ErMnO3 modulated its crystallographic structure from hexagonal to orthorhombic phase. Accompanied with the structural phase transition in ErMnO3, the magnetic properties are effectively modified. The Fe doped samples exhibit enhancement in antiferromagnetic ordering Néel temperature (TN) from 77 K (ErMnO3) to 280 K (ErFe0.5Mn0.5O3). The anomalies observed in the dielectric constant around TN in doped ErMnO3 samples indicate the coupling between electric and magnetic order parameters.
