摘要

The anomalous Nernst effect in a perpendicularly magnetized Ir₂₂Mn₇₈/Co₂₀Fe₆₀B₂₀/MgO thin film is measured using well-defined in-plane temperature gradients. The anomalous Nernst coefficient reaches 1.8 μV/K at room temperature, which is almost 50 times larger than that of a Ta/Co₂₀Fe₆₀B₂₀/MgO thin film with perpendicular magnetic anisotropy. The anomalous Nernst and anomalous Hall results in different sample structures revealing that the large Nernst coefficient of the Ir₂₂Mn₇₈/Co₂₀Fe₆₀B₂₀/MgO thin film is related to the interface between CoFeB and IrMn.
