Abstract
Magnetostriction of soft magnetic Fe_(80-x)Co_xSi_6B_(14)(10≤X≤78) amorphous alloy was investigated by using a small-angle magnetization rotation apparatus. Rapid quenching technique with using single roller was employed to prepare the amorphous ribbons. Saturation magnetizaion constant, λs, determined for alloys with various compositions. The magnetostriction reaches 22.2 ×10＾(-6) for X= 10 and decreases with increasing Co content. The magnetostriction reaches zero at around X= 74.5 and is -2.60 ×10＾(-6) at X=78. This result was compared with the magnetostriction of Fe-Co alloy. Metalloids do not affect the zero-magnetostriction of the amorphous.
