通过一种新的软组装方法合成了长度达10 μ m的中空钴中间球（480-850 nm）与60 nm厚的壳形成的磁性链。所制备的链状物的饱和磁化强度为37.5emu g（-1），剩余磁化强度为1.55emu g（-1），磁化率为ca.时速300公里时66欧提出了链状中空结构形成的可能机制。
Magnetic chains up to 10 mu m in length formed of hollow cobalt mesospheres (480-850 nm) with a 60 nm thick shell are synthesized by a new soft-assembly protocol. The obtained chains show a saturation magnetization of 37.5 emu g(-1), a remnant magnetization of 1.55 emu g(-1), and a coercivity of ca. 66 Oe at 300 K. A possible mechanism for the formation of the chainlike hollow structures is proposed.
