Synthesis and characterization of new Bi2FeNiO6 material using a citric acid assisted gel combustion technique

TLDR: In this article, the synthesis and characterization of a novel Bi2FeNiO6 material for the first time using a citric acid assisted gel combustion technique was reported, which exhibits ferrimagnetism with Neel temperature around 500 K Differential scanning calorimetry study also reveals a sharp phase transition at 500 K.

Abstract: Multiferroic materials, which show simultaneous ferroelectric and magnetic ordering, exhibit unusual physical properties–and in turn promise new device applications–as a result of the coupling between their dual order parameters BiFeO3 is currently considered the most promising candidate material for device applications of room temperature multiferroics However, its G-type antiferromagnetic behavior and high Neel temperature restrict the use of this material in potential applications We report the synthesis and characterization of a novel Bi2FeNiO6 material for the first time using a citric acid assisted gel combustion technique Magnetization studies reveal that it exhibits ferrimagnetism with Neel temperature around 500 K Differential scanning calorimetry study also reveals a sharp phase transition at 500 K These materials also exhibit good ferroelectric behavior with square type hysteresis with a remanent polarization (Pr) of 128 μC cm−2, saturation polarization (Ps) of 18 μC cm−2 and co
