采用化学气相沉积法制备了铁、钴原位掺杂的FeCo共掺杂的氧化锌纳米线。结构和成分分析表明，所制备的纳米线为单晶FeCo共掺杂。纳米线中没有发现FeCo团簇和其他第二相。As掺杂纳米线的居里温度高于300K。合成的−_x(FeCo)_xO纳米线的室温铁磁性使其在未来的自旋电子器件中具有很好的应用前景。
FeCo-codoped ZnO nanowires were synthesized by in situ doping with iron and cobalt using a chemical vapor deposition method. Structure and compositional analysis indicated that the as-prepared nanowires were single- crystalline and FeCo codoped. No FeCo clusters and other secondary phases were found in the nanowires. A Curie temperature higher than 300 K was observed from the as-doped nanowires. The room temperature ferromagnetic properties of the synthesized Zn1−x(FeCo)xO nanowire make it useful in future spintronic devices.
