摘要
本文简要介绍了奇点探测（ＳＰＤ）技术和磁晶各向异性理论，并利用ＳＰＤ技术在脉冲强磁场中测量了取向样品ＮｄＦｅ_（１０）Ｍｏ_２Ｃ_ｘ（ｘ～０．８）及其母体的磁晶各向异性场，通过取向样品的Ｘ射线衍射分析了样品的易磁化方同，发现ＮｄＦｅ_（１０）Ｍｏ_２Ｃ_（０．８）具备了研制高矫顽力永磁材料的内禀磁性。
In this paper,we briefly introduced the singular point detection (SPD) technique and the theory of magnetocrystalline anisotrpy,then we measured the magnetocrystalline anisotropy field of the magnetically aligned samples NdFe10Mo2C0.8 and NdFe10Mo2 by applying SPD technique in pulsed high magnetic fields. Meanwhile, we analyised the easy magnetization direction at room temperature of the samples. From that, we found the NdFe10Mo2C0.8 was qualified the intrinsic magnetic property for preparing the permanent magnet with a high coercivity.
