Outline of Final Research Achievements

Giant Magnetoresistance (GMR) films with a magnetic free layer of NiO sandwiched tri-layer was developed and its application to magnetic sensors was investigated. It is found that an exchange coupled CoFe/NiO/CoFeB tri-layers were obtained by using NiO thickness with 3 nm. A spin valve film with this tri-layer as magnetic free layer shows the magnetoresistance effect with 1.5% MR-ratio.
A spin valve film with a magnetic free layer of FeSiB/FeCoB was deposited on a cover glass and was applied to strain sensors. Output signals was increased with changing the strain from tensile strain to compressive strain.
