%X 本文采用真空电弧熔炼法制备了Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub>Laves相化合物&#65292;研究了其结构、磁性和磁致伸缩性能。X射线衍射实验和能谱分析结果表明&#65292;Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub>化合物呈现单一的Laves相。根据初始交流磁化率曲线确定Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub>化合物有两个自旋重取向温度T<sub>SR1</sub>和T<sub>SR2</sub>&#65292;分别对应易磁化方向从&lt;111&gt;到&lt;100&gt;和从&lt;100&gt;到&lt;110&gt;的转变。差示扫描量热法测量出Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub>化合物居里温度为643 K。在室温下&#65292;Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub>化合物在3 kOe和10 kOe磁场下&#65292;磁致伸缩(<i>&#955;</i><sub>||</sub>-<i>&#955;</i><sub>&#8869;</sub>)分别为810 ppm和1332 ppm。变温磁致伸缩研究表明&#65292;在3 kOe和10 kOe磁场下&#65292;磁致伸缩<i>&#955;</i><sub>3</sub><sub>k</sub> &#8805; 500 ppm和<i>&#955;</i><sub>1</sub><sub>0</sub><sub>k</sub> &#8805; 1000 ppm的温度跨度分别为155 K和280 K。这表明Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.9</sub>化合物具有宽温域磁致伸缩性能。<br>In this paper, Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub> Laves phase compounds were prepared by vacuum arc melting method, and their structural, magnetic, and magnetostrictive properties were investigated. The results of X-ray diffraction experiments and energy spectroscopic analyses showed that the Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub> compounds exhibit a single Laves phase. The Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub> compound was determined to have two spin reorientation temperatures, T<sub>SR1</sub> and T<sub>SR2</sub>, based on the Initial AC magnetic susceptibility, which corresponds to transitions from &lt;111&gt; to &lt;100&gt; and from &lt;100&gt; to &lt;110&gt; in the easy magnetic directionin, respectively. Differential scanning calorimetry measured the Curie temperature of the Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub> compound to be 643 K. At room temperature, the magnetostriction (<i>&#955;</i><sub>||</sub>-<i>&#955;</i><sub>&#8869;</sub>) of the Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub> compounds is 810 ppm and 1332 ppm for magnetic fields of 3 kOe and 10 kOe, respectively. Variable-temperature magnetostriction studies have shown that, for magnetic fields of 3 kOe and 10 kOe, the magnetostriction <i>&#955;</i><sub>3k</sub> &#8805; 500 ppm and <i>&#955;</i><sub>15k</sub> &#8805; 1000 ppm for temperature spans of 155 K and 280 K, respectively. This suggests that the Ho<sub>0.3</sub>Tb<sub>0.3</sub>Dy<sub>0.4</sub>Fe<sub>1.93</sub> compounds have wide temperature domain
