Temperature-dependent properties of the magnetic order in single-crystal BiFeO3

Hydrothermal synthesis and magnetic properties of single-crystalline BiFeO3 nanowires.

One-dimensional, single-crystalline BiFeO(3) nanowires presenting a diameter of 45-200 nm and a length from hundreds of nanometres to several microns have been prepared using an improved hydrothermal method. The characterization results of ZFC and FC magnetizations at different temperatures indicate that single-crystalline BiFeO(3) nanowires show a spin-glass transition below the freezing tempe...

Magnetic and electrical properties of single-phase multiferroic BiFeO3

Magneto-Optical properties of GaP single crystal

The temperature dependence of magneto-optical and magneto-photoconductivity measurements were carried out in the range of (200-330) K. A home made optical cryostat was used for the measurements. The measured room temperature value of the energy gap was found to be 2.211 eV. The temperature coefficient of energy gap was found to be -5.48×10-4 eV/K obtained by the optical absorption method and -4...

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...

investigation on elastic properties of ferromagnetic ni single crystal in magnetic field

elstic properties of nickel single crystal has been studied in magnetie fields ranging from 0 to 12 kgauss. comparison of the observed data shows that there might be an effect of changes in the rate of elongation due to the strangth of magnetic field in proportional region.
