(a) Measurement configuration of the Hall device, with magnetic field perpendicular or tilted. (b) Magnetization curve measured at 4 K using AHE. Black square shows the magnetization curve with MgO cap layer while the red line shows it with HfO2 cap layer. Magnetization curves are vertically shifted for clear comparison.
(a) Cross-sectional HRTEM image of Ta/[Pd/Co]/MgO. (b) Low magnification image of the same structure.
Magnetization curves measured with different currents, 100 μA, 1mA, and 3 mA. Magnetization curves are vertically shifted.
(a) Magnetization curves measured with H at (perpendicular), , and with the current of 3 mA at 4 K. (b) Magnetization curves measured at 6.3 K (3 mA), 20 K (100 μA), and 15 K (100 μA). R Hall of each curve is normalized for clear comparison.
(a) Magnetization curves measured at different T from 4 K to 50 K. The inset shows the H C values as a function of temperatures. (b) Magnetization curves measured at different T from 100 K to 300 K. Magnetization curves are also vertically shifted.
