MAGNETIC PROPERTIES AND MAGNETOELASTIC COUPLING MEASUREMENT IN LAYERED Fe-Co-B THIN FILMS

M. Maicas – D. Ciudad – C. Aroca – P. Sánchez – M. C. Sánchez – E. López

   This paper describes an optical cantilever-based system for the measurement of the magnetoelastic coupling of magnetostrictive thin films. The system is calibrated to evaluate the magnetoelastic coupling with no dependence on the Young modulus of the substrate. It has been applied to the measurement of the magnetoelastic coupling of a (Fe80Co20)80B20 amorphous alloy which appear to be a good magnetostrictive material for piezoelectric-magnetostrictive sensor applications.

Keywords: magnetic sensor, piezoelectric-magnetostrictive, magnetoelastic, FeCoB
