Abstract

In this study, epitaxial [Co(t nm)/Pt(1 nm)]₃₀ multilayer samples (t = 1, 0.5, 0.4, 0.3, 0.25 and 0.2 nm) were studied using X-ray measurements. The samples were prepared on Pt(1 1 1)/Mo(1 1 0) buffered Al₂O₃(1 1 2̄ 0) substrates in the MBE chamber. It was found that the Pt layer in the multilayer has a compressible strain of about 2-3.5% along the in-plane direction and the saturation magnetization is roughly proportional to this strain. Polarized X-ray absorption spectroscopy study showed that the Co layer is more like an FCC pseudomorphic structure for Co thickness less than 0.5 nm.
