摘要

We have prepared [Co₉₀Al₁₀/Cu]₃₀ multilayers by ion beam sputtering and studied the behavior of interlayer coupling, magnetoresistance, and the magneto-optical Kerr effect. For Co-Al/Cu multilayers, the in-plane saturation field, coercive force H_C and magnetoresistance ratio ΔR/R have been observed to oscillate with a period of about 0.9 nm, as a function of Cu spacer layer thickness. Furthermore, polar Kerr rotation θ_k in visible wavelength range also oscillates with the same period. The magneto-optical activities may be attributed to changes in the optical constants with the magnetic state.
