Abstract :
The lattice strain and the magnetic anisotropy have been examined for as-deposited and post-annealed Co/Pt and Co/Pd multilayers, which have been sputter-deposited on glass substrates with bias voltage. For Co/Pt multilayers, the interface anisotropy, Ks, has mainly the Neel type origin in the flat, smooth, and sharp interfaces, while the volume anisotropy, Kv, is sensitive to the magnetoelastic effect. For Co/Pd multilayers, the magnetoelastic effect plays the main role in Ks and Kv
