| 摘 要： | 采用氧化物工艺制备了钴掺杂的锰锌铁氧体。研究了钴掺杂量对其显微结构和磁性能的影响。结果表明,添加质量分数为0.02%的钴后,可以明显地改善材料的显微结构,使其磁滞常数(ηB)降低到1.5×10–7 mT–1,应用频率提高到200 kHz。

| Abstract: | MnZn ferrites were prepared by oxide process.Effect of different Co doping amounts on microstructures and magnetic properties of the Mn-Zn ferrite were investigated.The results show that after adding 0.02% Co(mass fraction) powder,the microstructure is improved remarkably,the hysteresis material constant is detracted to 1.5×10–7mT–1 and the applied frequency is enhanced to 200 kHz. |
