Abstract

In this work we present a study of the thermal stability of IrMn/CoFe exchange couples as a function of the thickness of the ferromagnetic (F) layer t(F). We find a monotonic decrease in the average blocking temperature < T(B)> with t(F) of up to 29% for t(F) = 12 nm. We have quantified the effect of the exchange field (H*) from the F layer on the antiferromagnetic (AF) layer and its effect on the thermal stability of the AF. H* can increase the degree of thermal activation by up to 44%.
