| Abstract: | 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. |
