Abstract :
Nanoelectrospun fibers of MFe2O4 (M = Ni0.25-Cu0.25-Zn0.5) were fabricated by electrospinning technique using PVP solution and and metal nitrate as starting materials. The as spun fibers were calcined at different temperatures of 500, 600, 700 and 800°C. The results from XRD indicated that the calcined nanofibers structure was face center cubic (fcc) with the lattice constant a = 0.83976 ± 0.00028 nm. SEM micrograph showed as-spun nanofibers with the average diameter of 480 ± 70 nm and the morphology of the nanofibers was changed to be more rough and wriggly after the calcinations with the diameters of 75-210 nm.
