We demonstrate structural and room temperature magnetic properties of Fe doped ZnO nanofibers (NFs) obtained by electrospinning followed calcination. The observed NFs, formed from crystalographically oriented, approximately 4.5 nm particles conglomerates, were 200 in diameter. reported synthesis ferromagnetic NFs is both facile economical, therefore suggested as a generic method fabricating biocompatible materials. major substrates selected for the (Zn, Fe) comprised relatively low toxicity Incorporating 10% into does not modify wurtzite crystal structure host material. No evidence impurity phase was detected either X-ray or electron diffraction. Magnetometry studies Magnetic Force Microscopy imaging reveal local order that persists up to temperature. suggest phenomenon due mechanism mediated presence oxygen vacancies and/or related iron-rich precipitates.
