In one embodiment, a desirable (e.g., substantially 100%) SOT switching probability is achieved in a SOT device by applying in-plane input current as one or more pulses having a tuned pulse width. In the case of a single pulse, pulse width may be selected as a single tuned pulse width or a range of pulse widths that avoid a specific pulse width determined to cause a switch-back response. In the case of multiple pulses, pulse width, a time interval between pulses and other factors such as intensities may be selected to prevent a switch-back response. Further, SOT switching speed may be achieved by reducing incubation delay through modification of an external magnetic field or input current density applied to the SOT device.
