E. Hristoforou et al., SOUND-VELOCITY IN MAGNETOSTRICTIVE AMORPHOUS RIBBONS AND WIRES, Journal of physics. D, Applied physics, 27(8), 1994, pp. 1595-1600
In this paper we present results on the dependence of the longitudinal
sound velocity of amorphous magnetostrictive ribbons and wires, teste
d either in the as-cast stage or after stress relief, on the magnetic
field along the anisotropy axis. Results show a variation of the sound
velocity that is in good agreement with results concerning the DeltaE
/E effect. Results are also given concerning the change in sound veloc
ity for magnetostrictive ribbons and wires before and after annealing.
These results can be used to decide the kind of treatment and biasing
field of such materials when they are to be used as magnetostrictive
delay lines.
