Abstract :
The magnetostriction of amorphous Pr0.2(Fe1-xCox)0.8 alloys (0 ¿ x ¿ 0.6) and Pry(Fe0.8Co0.2) × (Si0.43B0.57) × (0.7 ¿ x ¿ 0.85, 0.15 ¿ y ¿ 0.3, 0 ¿ z ¿ 0.3) alloys was measured in the temperature range from 77 to 400°K. The value of the magnetostriction ¿ (¿=(2/3) [¿1/1)¿-(¿l/l)¿]) for Pr0.2(Fe1-xCox)0.8 exhibits a maximum at x=0.2; it is about 760 × 10¿6 at 77°K and 260 × 10¿6 at room temperature. The temperature dependence of the magnetostriction is discussed in terms of the single-ion model.
