一、引言 铁基非晶材料是一种性能优良的磁性材料,与晶态硅钢相比具有明显低的损耗。但若按照它的电阻率和厚度来进行计算,就应该具有更低的损耗。因而对非晶材料,降低损耗机制的研究是国内外学者高度重视的研究课题。Kranse等人研究了使用表面刻痕、局部晶化,磁场处理等方法来降低非晶材料的损耗。石松耀等人研究了非晶合金的结构状态与铁磁损耗的问题。杨国斌等人研究了用析出相法改善Fe基非晶高频损 I. INTRODUCTION Iron-based amorphous material is a kind of excellent magnetic material with obvious low loss compared with crystalline silicon steel. However, if calculated according to its resistivity and thickness, it should have a lower loss. Therefore, the study on the mechanism of reducing the loss of amorphous materials is a research topic that scholars at home and abroad attach great importance to. Kranse et al. Studied the use of surface scoring, partial crystallization, magnetic field treatment and other methods to reduce the loss of amorphous materials. Shi Songyao, who studied the structural state of amorphous alloys and the issue of ferromagnetic loss. Yang Guobin and others studied the use of precipitation phase method to improve Fe-based amorphous high-frequency loss
