Image of FIG. 1.
FIG. 1.

(Color online) Device structure and the measurement. (a) Device and measurement setup. (b) Scanning electron microscopy image of the device. (c) Left panel: Relation between the core position and the MTJ output. Right panel: Relation between core direction and core rotation. (d) Device input and MTJ outputs for the up core and down core.

FIG. 2.

(Color online) Time-resolved detection of the vortex core switching. Device output as a function of time. Core direction can be read out as the amplitude.

Image of FIG. 3.
FIG. 3.

(Color online) Core switching induced by pulsed current. (a) Schematic wave form of the device input. The position of a pulsed current is shown in both time and phase domains. (b) Switching probability as a function of the pulse position with reference to the phase of the input AC current. (c) and (d) Device outputs for the pulsed current with δ = 0 and π, respectively. Input signals are also shown.

Image of FIG. 4.
FIG. 4.

(Color online) Demonstration of all-electrical operation of the vortex core memory. (a) Device output is shown together with the input signals. Every injection of the input pulse at any time switches the core direction (electrical data writing) and the core direction can be read out as the output amplitude. (b) Core switching induced by a pulsed current every one, two, and three period(s) of the input AC current.
