Abstract

Sputtered multilayers of Co0.6Fe0.2B0.2 and AlOx have been measured using grazing incidence x-ray scattering to determine the changes in layer and interface structure during in situ annealing. We confirm our earlier deduction of a sharpening of the interfaces on annealing up to 400 °C. This sharpening arises from reduction in chemical intermixing, not from change in topological roughness and provides an explanation for the enhanced tunneling magnetoresistance. The annealing is shown to result in a decrease in Co0.6Fe0.2B0.2 mean layer thickness and increase in the layer density. There is a commensurate increase in AlOx mean layer thickness while at the same time there is a reduction in the layer density. The increase in thickness could explain the corresponding increase observed in the resistance-area product.
