摘要
采用熔炼合金法制备DyPdSn样品,用切克劳斯基法把样品提拉成单晶,得到的单晶体横截面平滑而有光泽.根据X-射线衍射结果,确定DyPdSn化合物为斜方晶系(Pnma)TiNiSi型晶体结构;劳埃衍射斑点表明,该晶体为高质量单晶体.利用X-射线照射单晶体的b*面和c*面,在(020)和(006)晶面上获得较强衍射,从而确定出DyPdSn单晶的晶面.
The shows antiferromagnetic properties at low temperature.The polycrystalline ingots were prepared by arc-melting method.A single crystal was grown by using a Czochralski pulling method,the cross section of the single crystal is smooth and lustrous.The crystal structure were investigated by means of X-ray diffraction,DyPdSn compound crystalizes in the orthorhombic （Pnma）TiNiSi-type crystal struc-ture.X-ray Laue diffraction results show single crystal is high quality.The X-ray diffraction measurements were performed in the b＊ plane and c＊ plane,X-ray diffraction shows relatively strong reflections in （020） and （006）surfaces,which confirms growing direction of the DyPdSn single crystal.
