| description | <p>Abstract</p> <p>Magnesium ferrite (MgFe<sub>2</sub>O<sub>4</sub>) nanostructures were successfully fabricated by electrospinning method. X-ray diffraction, FT-IR, scanning electron microscopy, and transmission electron microscopy revealed that calcination of the as-spun MgFe<sub>2</sub>O<sub>4</sub>/poly(vinyl pyrrolidone) (PVP) composite nanofibers at 500–800 °C in air for 2 h resulted in well-developed spinel MgFe<sub>2</sub>O<sub>4</sub>nanostuctures. The crystal structure and morphology of the nanofibers were influenced by the calcination temperature. Crystallite size of the nanoparticles contained in nanofibers increased from 15 ± 4 to 24 ± 3 nm when calcination temperature was increased from 500 to 800 °C. Room temperature magnetization results showed a ferromagnetic behavior of the calcined MgFe<sub>2</sub>O<sub>4</sub>/PVP composite nanofibers, having their specific saturation magnetization (<it>M</it> <sub>s</sub>) values of 17.0, 20.7, 25.7, and 31.1 emu/g at 10 Oe for the samples calcined at 500, 600, 700, and 800 °C, respectively. It is found that the increase in the tendency of<it>M</it> <sub>s</sub>is consistent with the enhancement of crystallinity, and the values of<it>M</it> <sub>s</sub>for the MgFe<sub>2</sub>O<sub>4</sub>samples were observed to increase with increasing crystallite size.</p> |
