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 introduce the singularity detection (SPD) and magnetocrystalline anisotropy theory, and use the SPD technique to measure the magnetic crystal of NdFe_ (10) Mo_2C_x (x ~ 0.8) and its precursor in the pulsed magnetic field The anisotropy field shows that the NdFe_ (10) Mo_2C_ (0.8) possesses the intrinsic magnetic properties of high coercivity permanent magnet materials by analyzing the easy magnetization of the samples by X-ray diffraction of oriented samples.
