چکیده انگلیسی
Lanthanum manganite (LaMnO3) nanofibers were synthesized using electrospinning technique. The size and uniformity of these nanofibers were optimized by varying PVP concentration. X-ray diffraction analysis revealed the formation of single phase LaMnO3 nanofibers (average diameter ~400 nm) when the composite nanofibers were calcined at 600 °C. M″ and Z″ spectroscopic plots of impedance spectroscopy data confirmed the presence of two distinct electro-active regions referred to as the grain and grain boundary regions. The activation energies of the grain and grain boundary regions were 0.27 eV and 0.41 eV, respectively; which suggested two different transport mechanisms in these fibers.
