| Research Abstract |
The structural properties of the full epitaxial trilayer, AML[Fe/Co]n/Ag/AML[Fe/Co]n, on the Ag electrode have been confirmed by in situ reflection high-energy electron diffraction and transmission electron diffraction microscopy. A considerably large resistance-area product change and MR ratio (△RA > 3Ωμm2and MR ratio ＞5%) were confirmed even at thin AML[Fe/Co]n layer at room temperature (RT) in our spin-valve elements. The estimated values of βFand γF/N were 0.80 and 0.84±0.02, respectively. The intrinsic transport P of 0.60 was obtained for the AML epitaxial [Fe/Co]n superlattice by the point contact Andreev reflection (PCAR) method.The material design for Nano-contact MR device was obtained.
