Abstract :
In this study, the effects of post annealing temperature ranging from 250 degC to 350 degC on the giant magnetoresistance (GMR) ratio and conductance change (DeltaG) have been investigated. The structure of the GMR spin-valve consists of Cu (10 A) / IrMn (80 A) / CoFe (15 A) / NOL / CoFe (20 A) / Cu (28 A) / CoFe (tf) / NOL / Cu (10 A) / Al2O3 where tf is varied from 10 A to 200 A and NOL is a nano-oxide layer.
