Abstract

Electron microscopy, x-ray diffraction, and superconducting quantum interference device magnetometry were used for investigating FePt anf Fe ₃O ₄ nanotubes produced by hydrogen reduction in nanochannels of porous alumina. By reducing an appropriate Fe chloride anf Pt chloride mixture inside the pores of alumina templates, the nanotubes of FePt were synthesized. Thermal pyrolysis of iron nitrate led to the formation of Fe ₃O ₄ nanotubes in the same templates before hydrogen reduction. The tubes were found to be polycrystalline and the composition of the tubes strongly depended upon the reducing time and temperature, as indicated by the analysis of the microstructure.
