Abstract: A study is carried out on the effects of the metallic antiferromagnet (AF) gamma-FeMn and the AF-semiconductor NiO alloys on the polarity if anomalous Hall resistivity loops in perpendicularly biased [Pt(2 nm)/Co(0.4 nm)]15/AF (3 nm)/[Co(0.4 nm/Pt(2 nm)]15 (AF=FeMn, NiO) multilayers. The studies indicates that the hall resistivity exhibits negative polarity for AF=NiO and positive polarity for AF=FeMn.
