Fig. 6: 180° switching in IrMn3/Pt pillar, measured as a function of the write current amplitude.

From: Observation of current-induced switching in non-collinear antiferromagnetic IrMn3 by differential voltage measurements

Fig. 6

The color map corresponds to the amplitude and direction of the writing current applied before the differential voltage measurement. The graphs correspond to cases a when the current pulse is applied between electrodes 2 and 6, I2-6write, and b when the writing current is applied between electrodes 1 and 4, I1-4write. For both cases, the device resistance increases due to Joule heating as we apply more write attempts, and for current pulses above 18 mA the output voltage shows a switching behavior, indicating a threshold current density of ~36 MA/cm2 for switching in this structure. Each data point corresponds to the mean value of 170 consecutive measurements and the error bar to the standard deviation.
