We report a combined theoretical and experimental investigation of magnetic proximity and Hall transport in Pt/Cr bilayers. Density-functional theory indicates that interfacial magnetic moments can be induced in the Pt layer and a strong magnetocrystalline anisotropy with an out-of-plane easy axis arises in the antiferromagnet. A signal ascribed to the anomalous Hall effect is detected and associated to the interface between Pt and Cr layers. We discuss how this effect originates from the Berry curvature of the electronic structure at the interface and the correlation with the character of the proximity-induced magnetic moments.

Abstract
We report a combined theoretical and experimental investigation of magnetic proximity and Hall transport in Pt/Cr bilayers. Density-functional theory indicates that interfacial magnetic moments can be induced in the Pt layer and a strong magnetocrystalline anisotropy with an out-of-plane easy axis arises in the antiferromagnet. A signal ascribed to the anomalous Hall effect is detected and associated to the interface between Pt and Cr layers. We discuss how this effect originates from the Berry curvature of the electronic structure at the interface and the correlation with the character of the proximity-induced magnetic moments.
