摘要：

The surface magnetoelastic coupling coefficient B(s) is determined for cobalt-rich and iron-rich amorphous alloys by measuring the field and strain dependence of the spin polarization of secondary electrons emitted from their surfaces. B(s) is found to be approximately 3 times the bulk value for the cobalt-rich alloy and half the bulk value for the iron-rich alloy.
