| 摘 要： | 采用化学共沉淀法，在空心微球上包覆一层CoFe2O4，得到一种低密度的空心磁性微球．磁测量结果表明，磁场下退火制备的CoFe2O4样品反位缺陷减少，从而导致饱和磁化强度随退火磁场的增强而增大．吸波性能测试结果表明，包覆结构的CoFe2O4/空心球样品是一种轻质的微波吸收材料.

| Abstract: | The hollow low-density magnetic balls were synthesized through chemical precipitation method followed by the hollow glass sphere (cenosphere) coated with a layer CoFe2O4. Magnetic measurements suggested that the antisite defects of the magnetic annealed samples decreases, which results in the enhancement of saturation magnetization (Ms). The measurements of microwave absorbing properties show that the hollow spheres coated CoFe2O4 are the good and light-weight microwave absorbing materials. |
