Abstract

The magnetic properties, anti-corrosion properties and thermal stability of Cr₉₃Ga₇ bilayers and multilayer spin valves have been investigated. In corrosion resistance tests under 35°C with 90% humidity conditions, the MR ratio for Cr₉₃Ga₇, did not change, while the MR ratio for FeMn spin valve was lost after 15 days, CrGa/FeCo/Cu/FeCo spin valves were determined to be more thermally stable than CrGa/NiFe/Cu/NiFe and FeMn/NiFe/Cu/NiFe spin valves
