Implication

Experimental analysis reveals altered magnetoelastic coupling in amorphous alloy surfaces, indicating significant divergence from bulk magnetic behavior.

Key Points

To determine the surface magnetoelastic coupling coefficient in cobalt-rich and iron-rich amorphous alloys.
Measured the magnetic field and mechanical strain dependence of the spin polarization of secondary electrons emitted from the alloy surfaces.
Evaluated cobalt-rich and iron-rich amorphous alloy compositions to compare surface coupling constants with bulk values.
The surface magnetoelastic coupling coefficient for the cobalt-rich alloy was approximately 3 times its bulk value.
The surface magnetoelastic coupling coefficient for the iron-rich alloy was approximately half of its bulk value.
