“…The dielectric anomaly (related to relaxation) is observed at 270 ℃ and it shifts towards higher temperature with increasing Pr substitution. This relaxation may be due to the anti-ferromagnetic transition [14]. The magnitude of ε r in BPFO increases on increasing Pr content which is shown in Fig.…”

Abstract:The polycrystalline samples of Bi 1x Pr x FeO 3 (x = 0 and 0.1) were prepared by a solid-state reaction technique. Preliminary X-ray structural analysis has confirmed the formation of a single-phase compound. Studies of dielectric and impedance spectroscopy of the materials, carried out in wide frequency (1 kHz-1 MHz) and temperature (25-400 ℃ ) ranges, have provided many interesting results including significant decrement in tangent loss, structural stability, obeying Jonscher's universal power law, etc.

“…The efforts have been made to reduce the leakage current density by either introducing dopants or using different fabrication methods [12][13][14][15][16]. At present, many researchers are engaged in the enrichment of multiferroic properties of BiFeO 3 -relevant materials, using different trivalent dopants such as La [17], Mn [18], Sm [19] and Ti [20]. There are many reports on the ferroelectric and magnetic behaviors of BiFeO 3 .…”

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

“…A change in crystal structure of BFO was observed in BFO-doped Sm and Nd, which led to an improvement in piezoelectric properties, long-range ferroelectric, and canted antiferromagnetic orders [4][5][6]. Hou et al [7] reported an enhancement of magnetic properties in BFO materials where Y was substituted for Bi at the A site, and interpreted the magnetic enhancement as bring caused by shrinkage of the lattice constants.…”

Nd-doped BiFeO 3 materials were synthesized via a sol-gel method. The crystal structure, magnetic properties, and complex impedance spectroscopy of multiferroic Bi 1-x Nd x FeO 3 (BNFO) materials were investigated by Xray diffraction (XRD), Raman scattering, vibrating sample magnetometer (VSM), and complex impedance spectroscopy. Our results show that the lattice crystal constants (a, c) and the ratio c/a of BNFO materials decreased with increasing Nd concentration. All samples exhibited weak ferromagnetism at room temperature, and the magnetization of samples was enhanced by the presence of Nd 3+ ions. There was an enhancement in the spontaneous magnetization of BFO with increasing Nd concentration, which is attributable to the collapse of the spin cycloid structure.
