Figure 1: Device structure with measurement setup and Hall measurement for DW initialization.
From: Two-barrier stability that allows low-power operation in current-induced domain-wall motion
(a) Scanning electron microscope image of the device is combined with a schematic drawing of the measurement setup. The high-magnification inset shows a snapshot (obtained by micromagnetic simulation) of the pinned DW at the Hall cross. Color represents the internal magnetization direction. PG, pulse generator. (b) Result of the AHE measurement of the wire. The vertical axis is normalized AHE resistance (1 for upward magnetization and −1 for downward). (c) Normalized AHE resistance measured after initializing the DW by sweeping the magnetic field toward the negative direction. The snapshot images denote the magnetization configurations of the low-field (|H1|<|H|<|H2|) and high-field (|H|>|H2|) regions.
