| 英文摘要 | The cobalt ferrites with chemical composition co(1+x)zn(x)fe(2-2x)o(4) (r=0.0, 0.1, 0.2, 0.4) were obtained with conventional solid reaction. the zno-doped samples have lower lattice constant than cofe(2)o(4) by adjusting co ions to the octahedral sites. the results show that doping zno could extremely improve the magnetic properties. in comparison with pure cofe(2)o(4), the little zno-doped sample has higher permeability and much lower coercivity at the condition of a little decrease of magnetization saturation. sample with x=0.1 shows evident magnetostrictive effect at the magnetic field of 30-60 mt while pure cobalt ferrite sample does not, though the saturation magnetostriction decreases. these indicate that zno-doping improves the magnetostrictive sensitivity of the cobalt ferrites and have potential applications in magnetoelectric devices and magnetic detector. |
