| 摘 要： | 以铁、锰、锌和锶的硝酸盐为原料,以酒石酸为凝胶剂,采用sol-gel法制备了Sr2+掺杂的MnZn铁氧体(Mn0.6Zn0.4-xSrxFe2O4)。借助于XRD、SEM和振动样品磁强计(VSM)等表征手段,研究和分析了Sr2+掺杂量对所得MnZn铁氧体样品晶型、晶貌及磁性能的影响。结果表明:当Sr2+的掺杂量为0.10时,所得MnZn铁氧体样品的Ms为2.1646×105A/m。 |

| Abstract: | Magnetic materials of Sr2+-doped MnZn ferrites(Mn0.6Zn0.4-xSrxFe2O4) were prepared through sol-gel method using metal(Fe,Mn,Zn and Sr) nitrates as raw materials and tartaric acid as gelata.The influences of different Sr2+-doped amounts on the crystal phase,grain morphology and magnetic properties of the obtained MnZn ferrites were studied by using XRD,SEM and vibrating sample magnetometer(VSM).The results show that MnZn ferrites own the biggest saturation magnetization of 2.164 6×105 A/m when the doped amount of Sr2+ is 0.10. |
| Keywords: | non-metallic inorganic material MnZn ferrites tartaric acid Sr2+ doping sol-gel method |
