Investigation of multiferroic properties of binary compounds barium titanium yttrium ferric oxide

In this paper, multiferroic binary compounds BaTiO₃ (BTO) and YFeO₃ (YFO) were synthesized by the solid-state reaction method with varying concentration of x from 0 to 1.0 in the step size of 0.25. The prepared binary compounds have undergone the various characterizations like XRD, FTIR, Dielectric spectroscopy, and P–E loop analysis. The XRD of the compounds shows the single-phase structure symmetry varying from orthorhombic to tetragonal as the concentration of BTO increased. The bending and stretching vibration of the bond is confirmed by the FTIR. Dielectric results show the NTCR and non-Debye type relaxation in multiferroic compounds. The temperature-dependent dielectric properties revealed that the phase transition takes place in all the prepared compounds which confirms the ferroelectric nature of the compounds which makes promising application in the field of sensors. The P–E loop results show ferroelectric and leaky behavior of the compounds which have a significant potential in energy storage devices. The paramagnetic behavior of the composites at room temperature (RT) is confirmed by theoretical analysis of the polycrystalline samples.
