“…1(b)), the twin Bragg-peaks ( 104) and ( 110) gradually merge into a single peak corresponding to the lattice plan (110). This observation con rms the transformation of crystal symmetry from the rhombohedral structure (α-phase) to the cubic structure (β-phase) with space group Pm3m, as previously observed for Bi 1-x Eu x FeO 3 [19] and Bi 1-x Nd x FeO 3 [20]. Furthermore, the diffraction patterns of samples for Bi 0.85 Gd 0.15 FeO 3 (BGFO-15) and Bi 0.8 Gd 0.2 FeO 3 (BGFO-20) reveal a second structural transition from cubic (space group Pm3m) to orthorhombic structure (space group Pbnm) (β→γ).…”

Bi1-xGdxFeO3 \(\text{p}\text{o}\text{w}\text{d}\text{e}\text{r}\text{s} \text{w}\text{i}\text{t}\text{h} 0.00\le x\le 0.20\) were successfully synthesized by sol-gel process. X-ray analyses revealed the existence of a double structural transition from rhombohedral to cubic symmetry for \(x=0.10\) (first transition) and from cubic to orthorhombic symmetry for \(x\ge 0.15\) (second transition). Infrared spectroscopy allows the identification of different bending and stretching vibrations between the different ions. Magnetization hysteresis loops, recorded at room temperature, indicate a typical ferromagnetic-like behaviour. Additionally, differential scanning calorimetry measurements were also performed and discussed.

“…ME materials have a wide range of properties, and their use in numerous fields. These are quantum electromagnets, storage-media, magnetic field sensors, television, optical fibers, switches transducers, satellite communication, microwave actuators, multiple state memories, spintronic, microelectronic, and high-density ferroelectric RAM devices make them general marketing products [3] [4] [5]. Among active MFs, bismuth ferrite (BFO) is the reflection of both ferroelectric and G-type anti-ferromagnetic and properties at the same time.…”

A low cost and simple auto combustion method was used to prepare the Bi1-xSrxFeO3 (x=0.0, 0.04, 0.08, 0.12, 0.16) multiferroics samples. X-ray diffraction patterns confirms the integration of BFO pure phase nanoparticles with a perovskite structure of ABO3 type having space group R3c. Spherical structure with little agglomeration was observed during the morphological studies of the prepared samples. Sr2+ substituted at the A-site produces expansion in Raman modes and increased variations in cation site occupancy. Impedance analyzer was used to examine the frequency dependent dielectric parameters (ε´, tanδ), electric conductivity (σac), impedance (Z) and electric modulus (Mʹ and M″) of the samples in frequency between 20 Hz and 20 MHz). Maximum value of dielectric constant was observed at very low frequency for x=0.0 samples and it decreases by increasing concentration. Resonance peak was observed in tangent loss for high content of strontium. Maximum value of Impedance was observed at low frequency and it decreases by increasing frequency which is due to the grain and grain boundary contributions. It is observed that ac conductivity of the samples is found to be frequency dependent and it varies with doping of Sr in BFO. Improved polarization was examined in P-E loop of Sr doped BFO nanoparticles.
