通过 X 射线衍射、振动样品磁力计和标准应变仪技术研究了 SmZn1-xMnx 多晶晶体的结构、居里温度和磁致伸缩。研究发现，当x=0.2时，SmZn1-xMnx合金几乎是单一的Sm(Zn,Mn)相，具有CsCl型立方结构。当x <= 0.05时，SmZn1-xMnx合金的居里温度随着Mn的增加而迅速升高，并且在0.05 < x <= 0.2范围内逐渐升高。 SmZn化合物中Mn取代Zn对提高居里温度效果显着，当x=0.2时居里温度达到255 K。 SmZn1-xMnx合金的磁化强度在0 < x <= 0.2范围内随着Mn含量的增加而增加，磁致伸缩在0 < x <= 0.15范围内增加。 (c) 2006 年美国物理研究所。
The structure, Curie temperature, and magnetostriction of SmZn1-xMnx polycrystalline crystals were investigated by x-ray diffraction, vibrating-sample magnetometer, and standard strain gauge techniques. It is found that SmZn1-xMnx alloys are nearly a single Sm(Zn,Mn) phase with the CsCl-type cubic structure up to x=0.2. The Curie temperature of SmZn1-xMnx alloys quickly increases with increasing Mn when x <= 0.05 and gradually does in the range of 0.05 < x <= 0.2. The substitution of Mn for Zn in the SmZn compound has a marked effect on improving the Curie temperature and makes it reach 255 K when x=0.2. The magnetization of SmZn1-xMnx alloys increases with increasing Mn content in the range of 0 < x <= 0.2 and the magnetostriction increases in the range of 0 < x <= 0.15.
