Anomalous Nernst effect in Ir_22Mn_78/Co_20Fe_60B_20/MgO layers with perpendicular magnetic anisotropy
The anomalous Nernst effect in a perpendicularly magnetized Ir_22Mn_78/Co_20Fe_60B_20/MgO thin film is measured using well-defined in-plane temperature gradients. The anomalous Nernst coefficient reaches 1.8 microV/K at room temperature, which is almost 50 times larger than that of a Ta/Co_20Fe_60B_20/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 Ir_22Mn_78/Co_20Fe_60B_20/MgO thin film is related to the interface between CoFeB and IrMn.
