| 6. | Vibrating samples magnetometer ( vsm ) testing implied that yig were of ferrimagnetism , and cerium substitution had effects on saturation magnetization ( ms ) , residual magnetization ( mr ) and coercive force ( hc ) Vsm测试结果表明yig属于亚铁磁性物质, ce离子的掺杂对饱和磁化强度( ms ) 、剩余磁化强度( mr ) 、矫顽力( hc )都有一定的影响。 |
| 7. | The results of x - ray photoelectron spectrum ( xps ) demonstrated the ce ions in pure phase ce : yig ( x < 0 . 2 ) were in the state of trivalence . scanning electron microscope ( sem ) analysis showed conglobation of yig and ce : yig particles , whose size were smaller than 1 urn Xps的分析结果显示单相ce : yig ( x 0 . 2时)中ce离子是以正三价的状态存在,这与物相分析结果是一致的。 |
