Abstract

LaFeO₃ was prepared by solid state reaction method using Fe₂O₃ and La₂O₃ as starting materials. The crystallographic phase of the LaFeO₃ has been confirmed by X-ray diffractograms. Magnetic mass susceptibilities (χ_m) of the sample at different magnetic fields have been measured in the temperature range of 300-14 K. Thermal variations of χ_m and the observed ac magnetic hysteresis loop indicate the presence of magnetic ordering in LaFeO₃. Ferroelectric hysteresis loop observed at room temperature indicates the presence of ferroelectric ordering in LaFeO₃. Measured values of dielectric constant in the presence and absence of magnetic field confirmed that LaFeO₃ is multiferroic.
