发展了一种溶液外延法制备镍包铜纳米线。作为基本上单晶，在所得的复合Cu@Ni纳米线中的镍相在室温下表现出显着的导电性增强。在铁磁镍的辅助下，抗磁性铜纳米线对施加的磁场产生磁响应。
A solution-based epitaxial route to prepare nickel-sheathed copper nanowires has been developed. Being essentially single-crystalline, the nickel phase in the resultant composite Cu@Ni nanowires exhibits a significant enhancement in coercivity at room temperature. With the assistance of ferromagnetic nickel, diamagnetic copper nanowires become magnetically responsive to an applied magnetic field.
