“…The peak in the dielectric constant is attributed to a transformation from the antiferromagnetic order to the paramagnetic order,indicating an effect of disappearing magnetic order as compared to electric order and attests to magneto-electric coupling in the samples. This type of anomaly near the Nèel temperature has also been predicted by several studies [53][54][55][56][57][58]. Here, the peaks show a diffuse nature.…”

Multiferroic Bi 1−x CexFeO 3 (x = 0.05, 0.1, 0.15, 0.2) nanoparticles were prepared using an auto-combustion method. The effect of cerium substitution on the crystal structure, electrical and magnetic properties of BiFeO 3 (Bismuth Ferrite) was studied. X-raydiffraction spectra revealed that Ce substitution increases the lattice parameters. The average particle size estimated from TEM images is less than 50 nanometers. According to the magnetic hysteresis loops, it was found that the enhanced magnetization which results from increasing Ce concentration is attributed to the nanoparticle size and enhanced ferroelectric polarization. The magnetization and ferroelectric polarization were found to exhibit an exotic mutual relationship. The samples were found to exhibit relaxation of dielectric polarization. This rare combination of Ce doped BiFeO 3 by auto-combustion method has not been reported before.

“…Because of room-temperature coupling between ferroelectric and magnetic order parameters, it brings forth a novel phenomenon known as magnetoelectric effect (ME), in which polarization can be tuned by magnetic field and vice versa. This coupling provides an additional opportunity for the design of magnetoelectric and spintronic devices [2][3][4]. Multiferroic materials have gained tremendous attention on account of their potential applications in various fields, such as bubble memory device, microwave, satellite communication, audio-video, digital recording [4,5], sensor, multiple state memory element, electro-ferromagnetic resonance  device [6], thin film capacitor, non-volatile memory [7], optoelectronics, solar energy device [4], highdensity ferroelectric magnetic random access memory [8], and permanent magnet [9].…”

“…Xu et al [21] observed a room-temperature saturated magnetic hysteresis loop in Zn-doped BiFeO 3 ceramic by rapid sintering method. Chaudhari et al [3] observed a superparamagnetic nature at 5 K and weak ferromagnetic behavior in BiFe 1x Zn x O 3 (0.05≤x≤ 0.15) ceramic by solution combustion method (SCM). The multiferroic Bi 1x Ca x FeO 3 ceramic presents enhanced magnetic property which suppresses spin modulated structure [22].…”

Ni-doped BiFeO 3 powders with the composition BiFe 1x Ni x O 3 (x = 0.05, 0.1 and 0.15) were prepared by a self-propagating high-temperature synthesis (SHS), using metal nitrates as oxidizers and glycine as fuel. The X-ray diffraction (XRD) patterns depict that Ni-doped BiFeO 3 ceramics crystallize in a rhombhohedral phase. The scanning electron micrographs of Ni-doped BiFeO 3 ceramics show a dense morphology with interconnected structure. It is found that, the room-temperature magnetization measurements in Ni-incorporated

“…The electric properties of Bi 2 (Fe 1 À x Al x ) 4 O 9 (0 rxr 0.25) ceramics are evaluated by measuring room temperature P-E hysteresis while the loops become more slip with higher Al 3 þ concentration. Usually, the unsaturated behavior and partially reversed polarization usually associate with leakage current [29]. To prove it, the J is measured for all the samples at room temperature, and the results of the measurement are shown in Fig.…”
