Abstract
Magnetic chains up to 10 μm 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.Keywords
