Abstract
AbstractHexagonal close‐packed (hcp) cobalt nanowires with diameters of 150–300 nm and lengths of up to several hundreds of micrometers have been synthesized by a hydrothermal reduction method. These cobalt nanowires were generated by the reduction of cobalt(II) citrate complexes by hypophosphite (H2PO2–) in basic solution at 160 °C. High‐resolution TEM and SAED reveal that the as‐prepared Co nanowires have a single‐crystalline structure with a [001] growth direction. The room‐temperature hysteresis loop of these nanowires shows a ferromagnetic behavior with enhanced coercivity. A formation mechanism for these Co nanowires is proposed.
