Tailoring of the soft magnetic property and uniaxial anisotropy of magnetostrictive films by interlayer

Laminated amorphous FeSiBC films with various spacer layers, including Cu, Co 0.45 Cu 0.55 , Co 0.8 Cu 0.2 , and CoFe, were prepared in order to study the effect of interface structure and magnetic exchange interaction on the magnetic softness and uniaxial anisotropy of multilayered film. It is foun... Full description

description: Laminated amorphous FeSiBC films with various spacer layers, including Cu, Co 0.45 Cu 0.55 , Co 0.8 Cu 0.2 , and CoFe, were prepared in order to study the effect of interface structure and magnetic exchange interaction on the magnetic softness and uniaxial anisotropy of multilayered film. It is found that laminating FeSiBC film with thin nonmagnetic or weak magnetic spacers yields much lower coercivity and higher remanent magnetization than those with magnetic spacers. Optimal films with the desired properties of H c  ∼ 1.5 Oe, M r / M s  = 95%, and H k  ∼ 16 Oe were obtained. Therefore, it is confirmed that the exchange interaction constant of spacer layer plays a more important role than that of interface structure. Furthermore, laminating FeSiBC with nonmagnetic layers only slightly changes magnetostrictive coefficient.
