英文摘要	Hollow Fe70Co30 nanospheres have been prepared in aqueous solution with KBH4 as the reducing agent and sodium dodecyl sulfonate ( SDS) as the stabilizing agent. The diameter of these spheres is about 100 - 200 nm and the shell thickness is about 15 - 20 nm. By transmission electron microscopy ( TEM) analysis, it was found that these hollow spheres formed via an in situ galvanic replacement reaction between iron nanoparticles and the cobalt cation. These hollow Fe70Co30 spheres exhibit surface plasmon resonance ( SPR) absorption in the ultraviolet - visible spectrum. The magnetic properties of the as- prepared hollow Fe70Co30 nanospheres and of a sample annealed at 573 K were studied. Annealing the product can greatly enhance the saturation magnetization Ms and coercivity H-c.
