This paper is to study the object of Mn - Zn ferrite powder, which is an important non-metallic magnetic materials, because of their narrow hysteresis loop, high magnetic permeability and high resistivity, high Curie temperature and the low loss character

这种磁性微粒经局部注射或经动脉导管注入瘤体后，在交变磁场作用下吸收电磁波转化为热能使肿瘤区升温达所需的治疗温度(41～46℃)，以杀死肿瘤细胞，而不含磁微粒的正常组织不受损，正逐渐成为医学上肿瘤热疗技术的研究对象。
