Polycrystalline samples of Ho doped BiFeO3 were prepared by solid state reaction method and effect of partial substitution of Ho on dielectric, magnetic and ferroelectric properties was studied. High temperature dielectric results show two dielectric anomalies both in ɛ and tan δ, out of which, anomaly at higher temperature (∼400 °C) could be ascribed to antiferromagnetic Néel temperature which, is a signature of magnetoelectric coupling. The magnetic moment is greatly improved and the maximum magnetization was found to be 0.736 emu/g. Saturated ferroelectric hysteresis loops were observed for Bi0.95Ho0.05FeO3 with remnant polarization (Pr) = 1.59 μC/cm2, maximum polarization (Pmax) = 2.56 μC/cm2 and coercivity (Ec) = 5.45 kV/cm. We have conducted comprehensive magnetoelectric and magnetodielectric properties at room temperature. Magnetic field induced ferroelectric hysteresis loop observed in Bi0.95Ho0.05FeO3 is of prime importance.
► In this paper we have studied the effect of small substitution of Ho at Bi site on the multiferroic properties of (Bi0.95Ho0.05FeO3). ► We have reported magnetic properties at room temperature as well as low temperatures. ► Enhanced ferroelectric (P–E) loops are observed for Bi0.95Ho0.05FeO3 at various frequencies. ► The effect of magnetic field on the ferroelectric and dielectric properties of the modified compound is studied. ► The compound shows enhanced multiferroic and magnetoelectric properties at room temperature.
