Evidence of the Topological Hall Effect in Pt/Antiferromagnetic Insulator Bilayers
Abstract
The topological Hall effect has been a primary indicator of nontrivial spin textures in magnetic materials. We observe the evidence of the topological Hall effect in Pt/Cr2O3 bilayers grown on Al2O3 (0001) and Al2O3 (112¯0), where the Cr2O3 epitaxial film is an antiferromagnetic insulator. The Pt/Cr2O3 bilayers exhibit topological Hall resistivity for Cr2O3 thicknesses below 6 nm near and above room temperature, which is above the Neel temperature of Cr2O3, revealing the key role of thermal fluctuations in the formation of spin textures. In conclusion, the similarity of topological Hall signals in (0001)- and (112¯0)-oriented Cr2O3 films indicates that the emergence of spin textures is insensitive to crystalline orientation.
