Dynamic Magnetoelastic Effects in the Fe80Si10B10 Amorphous Ribbons Associated with Surface Crystallization
The dynamic magnetoelastic properties of the Fe80Si10B10 amorphous alloy at different stages of the thermal crystallization process were studied by the method of double electromagnetic acoustic transformation. An anomalous increase in the dynamical magnetostriction and ultrasound damping and a decrease of sound velocity were found. According to the Mössbauer spectroscopy data, they are related to the formation of a component of magnetic moments that is perpendicular to the ribbon surface.
