摘要
本文利用自制的磁致伸缩测量仪和“ｊｕｍｐ”效应测量仪研究了在一定压强了多晶（Ｔｂ、Ｄｙ）Ｆｅ２棒的磁致伸缩，发现加压时，在一定工艺条件下制作的（Ｔｂ、Ｄｙ）Ｆｅ２棒会有磁致伸缩的变化。卸载后经过热处理，磁致伸缩值在不加压时也会维持一个高值。
Manetostriction of (Tb、Dy) Fe2 twined-crystal can produce 'jump' effect under the proper pressure. This have not been reported in the articles on the multicrystal (Tb、Dy)Fe2. With the aid of the self-made magnetostriction measuring instrument and the 'jump' effect measuring instrument, the magneto-striction of (Tb、Dy) Fe2 under the proper intensity of pressure was observed. The pressure being given, we would find the change of magnetostriction of (Tb、Dy) Fe2 which is made under definite technological condition. After the pressure in unloded, the sample which heat-treated at the definite temperature can keep a high value of magnetostriction. This is an important phenomenon which we should make much of.
