Magnetic properties of large-area one-dimensional WO2 and MoO2 nanorods

Large-area one-dimensional (1D) monoclinic WO2 and MoO2 nanorods in the space group P2(1)/c were synthesized by reactive thermal evaporation. The as-synthesized 1D WO2 and MoO2 nanorods become soft magnetic materials at 10 K, implying that structural or magnetic transitions occur. There are large differences in saturation magnetization, the coercive field, and remanence between the 1D WO2 and MoO2 nanorods, although both 1D nanorods have a similar shape. (C) 2006 Elsevier B.
