Study of structural, magnetic and electrical properties on Ho-substituted BiFeO3

Structural, Magnetic and Photocatalytic Properties of BiFeO3 Nanoparticles

Single phase BiFeO3 (BFO) nanoparticles as a visible light photocatalyst were successfully synthesized by thermal decomposition of the glyoxylate precursor. The glyoxylate precursors were formed by the redox reaction between ethylene glycol and nitrate ions. The phase evolution, structure and optical properties of BFO nanoparticles were characterized by X-ray diffraction, electron microscopy an...

Magnetic and electrical properties of single-phase multiferroic BiFeO3

Pressure effect on structural and vibrational properties of Y-substituted BiFeO3.

The structural and vibrational properties of 5% Y-substituted BiFeO3 under pressure have been investigated using synchrotron x-ray diffraction (SXRD) and Raman scattering measurements. At a pressure below 30.3 GPa, distinct changes in the Raman spectra and SRXD pattern show evidence for one pressure-induced structural transition from the polar rhombohedral R3c phase to the nonpolar orthorhombic...

Effect of Ba Substitution on the Structural and Magnetic Properties of BiFeO3

Bi1−xBaxFeO3 (0 ≤ x ≤ 0.3) nanopowders were synthesized using sol-gel technique. The structural and magnetic properties were investigated using X-ray diffraction, SEM and VSM. As Ba2+ doping concentration was increased, the structure of the samples changed from rhombohedral to tetragonal or monoclinic. The structural change might be an important factor for achieving the ferroelectric properties...
