摘要: |
制备了低居里温度的磁热Mn-Zn铁氧体,对样品进行了磁滞回线和磁热效应的试验及测定,结果表明,试样在交变磁场下,具有明显的磁热效应.尝试以降温法测量居里温度,所得结果验证了居里温度与试样组成的关系. |

Abstract: |
The thermomagnetic Mn-Zn-ferrite, which has low Curie temperature was prepared. The hysteresis loop, thermomagnetic effect and Curie temperature of samples were tested. It was studied to measure the Curie temperature by cooling method. The results prove the relationship of Curie temperature and the composition. And in the alternative magnetic field, the samples have the obvious thermomagnetic effect. |
Key words: Mn-Zn-ferrite,Curie temperature,thermomagnetic effect |
