摘要：
We report a large enhanced anomalous Hall effect (AHE) in the Co/Pt multilayers sandwiched by two MgO layers. The Hall resistivity (rho(xy)) was over an order of magnitude larger than that in pure Co/Pt multilayers. By optimizing the thickness of MgO layers, a high field sensitivity value of 2445 V/A T for Hall sensors was achieved. The enhancement of AHE is mainly attributed to the MgO-Pt interfacial effect.
