矫顽

• 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。
• Especially y - ni - 22fe , which have been widely used in industry things such as magnetic record heads , transformers or magnetic shielding materials due to its high permeability , low coercive force and relatively high saturation magnetization
  特别是- ni - 20fe合金，因其较高的磁导率、饱和磁化强度、低的矫顽力而广泛用于磁记录头、变压器和磁屏蔽材料等。
• The hysteresis loops were detected , it is found that the remanent polarization and the conceive field of the ceramics deceased with the dope of ba2 + . in the composition range of mpb , the conceive field exhibit the lowest value
  测试了样品的电滞回线，发现batio _ 3的掺入有效降低了nbt基陶瓷的剩余极化强度和矫顽场，在准同型相界组成点，矫顽场达到最小值。
• Through the research of the present stage , the researching results can provide the reference for low - temperature sintering the low coercively lizn ferrite which is important to improve the performance of microwave ferrite for phase shifter
