Mn添加对锂铁氧体应力敏感性的影响

Effects of Mn addition on the stress sensitivity of lithium ferrite

采用传统氧化物法制备了Li铁氧体材料,研究了Mn添加对材料电磁性能的影响。结果表明,添加适量Mn可有效降低材料对应力的敏感性,Mn添加量对材料密度影响较小,样品饱和磁化强度随Mn添加量增加而减小。

The lithium ferrite materials were prepared by conventional oxide method.The effects of Mn addition on the electromagnetic properties of lithium ferrite were investigated.The experimental results showed that proper amount of Mn addition can reduce the stress sensitivity of lithium ferrite.As a result,with increasing Mn addition no obvious change occurs in density,while saturation magnetization decreases.
