Abstract: | Amorphous Fe100-xBx(11.5 ≦ x ≦ 22) alloys having the invar characteristics were prepared by a single roller quenching method to investigate the magneto-volume effect. Forced volume magnetostriction, ?ω/?H, increased remarkably with decreasing boron content and the maximum value obtained was about 90 × 10?10 Oe?1 at 11.5 at.% boron. The estimated value of the pressure dependence of the Curie temperature, ?Tc/?P, was considerably large, being comparable to those of crystalline FeNi invar alloys. The ?Tc/?P curve plotted as a function of Tc approximately fitted Wohlfarth's expression. |
