Abstract

The magnetic and magneto-optical properties of Pd/Co multilayered films prepared by rf sputtering have been investigated. The perpendicular magnetic anisotropy of films increases as the layering period Â¿ and Co content are decreased. The maximum value obtained for the anisotropy KÂ¿ was 3.8 Ã— 10⁶ erg/cc, where Â¿ and the Co content were 11 Ã… and 28 at% respectively. The saturation magnetization increases as Â¿ decreases, approaching the same value as for the alloys. The Kerr spectra of multilayered films and of alloy films are alike in having a peak near the wavelength of 400 nm, and they are almost the same when Â¿ ≪ 15 A. These results suggest that the perpendicular anisotropy results from compositionally modulated structures with interfacial alloying rather than wdth sharp bilayer interfaces.
