Description

Highlights: • The electronic transport properties in Co/Pt multilayers are studied. • Thermally stable AHE feature is obtained in HfO2/Co/Pt/Co/Pt/Co/HfO2 multilayers. • Co/HfO2 interfaces have a vital effect on AHE in Co/Pt multilayers after annealing. - Abstract: The effect of annealing on the anomalous Hall effect (AHE) in perpendicular Co/Pt multilayers sandwiched by HfO2 layers has been studied. It was found that thermally stable AHE features can be obtained in perpendicular Co/Pt multilayers with the introduction of two Co/HfO2 interfaces, leading to the improvement of the skew scattering contribution to the AHE after annealing. On the contrary, thermally stable AHE behavior cannot be observed in Co/Pt multilayers sandwiched by Pt layers or MgO layers because of Co–Pt interdiffusion during annealing.
