A new metallic glass, (METGLAS®alloy) Co 74 Fe 6 B 20 , has been identified which exhibits ∼ zero magnetostriction ( |\lambda_{s}| ). 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 Co 74 Fe 6 B 20 glass exhibit exceptional low-field magnetic properties: H_{c} = 0.035 Oe, B_{r} = 9800 gauss and \mu_{max} = 280,000 .
