FIG. 1.

(Color online) (a) Schematics of nanopillar structure. The pillar has a diameter of . The vortex structures in both layers are uniform, and each layer contains a single vortex core located at the center of the disk. The initial vortex states of the Py (b) and Co (c) layers are identified as CCW-positive based on their chirality and positive polarities of the core magnetizations.

FIG. 2.

(Color online) Nonequilibrium magnetization distributions of at selected time points after the onset of a current pulse of with duration: (a) , (b) , (c) , (d) , and (e) after the current pulse. (f) distribution captured at after the current pulse. Each arrow indicates the averaged local magnetization from four unit cells.

FIG. 3.

(Color online) Three-dimensional trajectory of the magnetization averaged over the area of in diameter, shaded area in the inset. (a) The trajectory reveals an initial rapid rotation of from to , and the spin torque induced by the current pulse tilts the magnetization vector out of the plane. (b) Dynamic response of components. Note that the scale of the axis is an order of magnitude smaller than that in (a). This indicates that resists the spin-transfer torque by the spin-polarized electrons partly reflected from the Cu/Py interface.

FIG. 4.

(Color online) Nonequilibrium magnetization distributions of at selected time points after the onset of a current pulse of with duration: (a) , (b) , (c) , (d) , and (e) after the current pulse. Image (f) is captured for at . Each arrow indicates the averaged local magnetization from four unit cells.
