Study on Crystal and Magnetic Structures of PrFe10.2Mo10.2Co0.3 Alloy By Neutron Diffraction
【摘要】 为研究PrFe10.2Mo1.5CO0.3永磁合金样品中Co的加入对磁性能的影响,采用粉末中子衍射研究方法确定了它的晶体结构与磁结构.Reitveld峰形精修法对中子衍射数据的拟合得到了Mo择优占据8i替代晶位、Co择优进入8j替代晶位的的结果.Co替代8j晶位部分Fe导致磁矩和和磁化强度增强,居里温度升高.
【Abstract】 To find out the effect of Co on magnetic properties of PrFe10.2Mo1.5CoO.3Permanent magnetic alloy, the cryatal and magnetic structures of the alloy aredetermined by powder neutron diffraction. Reitveld analysis of the neutron diffractiondata indicates that Mo prefers the 8j site while Co prefers the 8j site. The experimentalstudy shows that the magnetic moment and the saturation magnetization are enhanced,and the Curie temperature is raised due to the 8j crystal site Fe is replaced by Co.
