Abstract

The properties of Co/CoO_x exchange-coupled spin valves are explored at temperatures to 5K. The spin valve structure is: 100 Å CoO_x/30 Å Co/30 Å Cu/10 Å Co/50 Å NiFe/50 Å Ti. Our discovery is the considerable differences between the properties of the spin valves for which the CoO_x layer is prepared in different O₂ concentrations.
