Magnetron sputtering was used to prepare spin valves with the Ta/Ni sub(80)Fe sub(20)/Co sub(90)Fe sub(10)/Cu/Co sub(90)Fe sub(10)/Ru/Co sub(90 )Fe sub(10)/Fe sub(50)Mn sub(50 )/Ta composition. Changes in the functional characteristics of the spin valves were studied in a temperature range of-180 to +160 degree C. The maximum temperature at which the functional characteristics of spin valve remain unchanged was shown to depend on the relationship of thicknesses of Co sub(90)Fe sub(10) layers separated by the Ru interlayer.
