Abstract
Amorphous Fe1-xDyx ribbons with compositions close to the eutectic com position have been studied. At room temperature, the magnetization is not zero. When heated to T > 350 degrees C, a significant increase of the magnetization is observed indicating the appearance of the Fe2Dy p hase. This is also confirmed by differential scanning calorimetry and elongation measurements. After heating to 520 degrees C, we obtained a magnetization curve typical of the Fe2Dy compound. Furthermore, a par ticular phenomenon associated with a small increase of magnetization i s detected between 120 degrees C and 300 degrees C. It was interpreted in terms of the release of constraints related to the magnetostrictio n. This phenomenon disappears for x greater than or equal to 0.75.
