Abstract

Exchange biasing of ferromagnetic layer deposited on the antiferromagnetic superlattice was investigated in (Co70Fe30/Ru)29.5/Ru/Co90Fe10 multilayers. Uniaxial magnetic anisotropy (KAF) was induced and tuned in the antiferromagentic superlattice by uniaxial substrate bending method through the inverse effect of magnetostriction. The exchange bias increased and tended to be saturated with increasing the KAF, while it was not observed at KAF=0.
