Giant MR of CoFe/Cu Spin-Valves.

Abstract
Co90Fe10/Cu spin-valve structures were prepared by the RF and DC magnetron sputtering methods. X-ray diffraction data showed that the spin-valves on a sapphire substrate exhibited good fcc (111) preferred orientations. The maximum value of Δρ/ρ0 was 11%, which was larger than that obtained for Co/Cu spin-valve structures.
