摘要：

An enhanced anomalous Hall effect (AHE) is observed via interface modification in MgO/[Co/Pt](2)/Co/MgO multilayers, due to the insertion of a Hf metal layer at the Co/MgO interface. It is shown that the saturation anomalous Hall resistivity is 215% larger than that in the multilayers without Hf insertion. More importantly, thermally stable AHE and perpendicular magnetic anisotropy features are obtained in MgO/[Co/Pt](2)/Co/Hf/MgO multilayers. The AHE is improved for sample MgO/[Co/Pt](2)/Co/Hf/MgO by annealing, which is attributed to the enhancement of the side jump contribution. (C) 2015 AIP Publishing LLC.
