Abstract: Diluted magnetic semiconductor (DMS) nanowires (NWs), Mn-doped CdSe, were successfully prepared in a gold-catalyzed vapor-transport deposition process. It was demonstrated for the first time that upon incorporation of Mn of very limited concentrations, the CdSe NWs exhibited enhanced ferromagnetism at T < 40 K and turned superparamagnetic at relatively high temperatures. This finding would extend the application range of DMS NWs into the biolabeling and bioimaging fields.
