磁弹性测量是在成分为(Fe_(0.79)Co_(0.21))_(75+x)的金属玻璃中进行的。Si 15 −1.4xB10+0.4x(x= 0,2,4,6,8,10)的共振-反共振方法。在某些组合物中观察到高值的k(磁弹性耦合系数)和Δ Y效应,在淬火状态下达到0.7叉和50%的Δ Y。退火处理进一步提高这些值。
Magnetoelastic measurements are performed in metallic glasses of composition (Fe0.79Co0.21)75+x. Si15−1.4xB10+0.4x(x= 0, 2, 4, 6, 8, 10) by means of the resonance‐antiresonance method. High values ofk(magnetoelastic coupling coefficient) and of the ΔYeffect are observed in some compositions, reaching 0.7 forkand 50% for ΔYin the as‐quenched state. Annealing treatments further improve these values.
