- 論文の詳細を見る
The electrical resistivity p in various magnetic fields and the structure of [Co(1.02nm)/Cu(t_<Cu>)]_<25> magnetic multilayers (MML) have been investigated to clarify the relationship between the transport properties (electrical resistivity and magnetoresistance) and structure (orientation and strain of these layers). The in-plane compressive strain s of antiferromagnetic (AF) Co/Cu MML with t_<Cu>=1.05nm is larger than that of ferromagnetic (F) Co/Cu MML with t_<Cu>=0.76nm. Furthermore, it is found that ε of the AF-Co/Cu MML is proportional to the magnitude of giant magnetoresistance, whereas that of F-MML is independent of magnetoresistance. This implies that the strain in AF-Co/Cu MMLs showing GMR is closely related to the spin-dependent scattering of conduction electrons at interfaces.
