摘要

Anomalous Hall effect at room temperature in perpendicular Hall balance with a core structure of [Pt/Co]₄/NiO/[Co/Pt]₄ has been tuned by functional CoO layers, where [Pt/Co]₄ multilayers exhibit perpendicular magnetic anisotropy. A giant Hall resistance ratio up to 69900% and saturation Hall resistance (R_S^P) up to 2590 mΩ were obtained in CoO/[Pt/Co]₄/NiO/[Co/Pt]₄/CoO system, which is 302% and 146% larger than that in the structure without CoO layers, respectively. Transmission electron microscopy shows highly textured [Co/Pt]₄ multilayers and oxide layers with local epitaxial relations, indicating that the crystallographic structure has significant influence on spin dependent transport properties.
