Abstract :
A new metallic glass, (METGLAS®alloy) Co74 Fe6 B20 , has been identified which exhibits ∼ zero magnetostriction ( 
). The saturation induction of this new alloy, 11.8 kG, is approximately twice that reported for other non-magnetostrictive glasses with similar transition-metal (TM) content but including the metalloids P and Al or Si in addition to B. This larger magnetization results from the weaker hybridization of the TM d-bands with the valence bands of boron than with those of other metalloids. Due to the absence of magnetostriction, no coupling between winding stresses and magnetic properties exists. Hence, as-quenched/as-wound toroids of Co74 Fe6 B20 glass exhibit exceptional low-field magnetic properties: 
Oe, 
gauss and
