Magnetostriction and Magnetostrictive Susceptibility of Fe-Tb and Fe-Pd Composite Thin Films

Abstract

Influences of magnetostriction and magnetostrictive susceptibility of composite mover device of Fe Tb alloy thin film coated with Fe Pd alloy thin films on one side surface of silicon substrate prepared by DC magnetron sputtering process were investigated. The magnetic field induced the bending motion at 1000 kA/m. The magnetostriction and its susceptibility of the device film approximately corresponds to the average of values of Fe Tb and Fe Pd positive magnetostrictive thin films.
