摘要

One-dimensional magnetic materials find several applications in modern technology. Co-Fe alloys and their oxides CoxFe2-xO3 (0 ≤ × ≤ 0.7) were prepared using a very simple and novel technique. The X-ray diffraction patterns confirm the coexistence α-Fe2O3 and ε-Fe2O3 phases in the as-prepared as well as the sample sintered in N2 atmosphere. In contrast, samples sintered in H2 atmosphere could provide Co-Fe alloys and α-Fe2O3 composites. Nanorod shapes for oxide samples were corroborated by scanning and transmission electron microscopy. A reasonably high coercivity value (~118 mT) was observed for such rods, whereas a sufficiently high saturation magnetization value near 162 Am2/kg was obtained for other types of composites.
