Abstract

The properties of Co/CoOx exchange-coupled spin valves are explored at temperatures to 5K. The spin valve structure is: 100 Å CoOx/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 CoOx layer is prepared in different O2 concentrations.
