FIG. 1.

(a) Illustration of the typical structure of spin valve with IP and OP dual polarizers. Current flowing from the OP polarizer to the IP polarizer is defined as the positive current. (b) Illustration of spin-torque orientations generated by IP polarizer (TIP) or OP polarizer (TOP). (c) Temporal oscillation evolution of the free layer magnetization components.

FIG. 2.

Dependence of the oscillation frequency of the free layer magnetization on the spin-torque strengths at a fixed OP spin-torque (a) and a fixed IP spin-torque (b).

Image of FIG. 3.
FIG. 3.

(a) Temporal evolution of magnetization switching driven by a single current pulse with different durations. The initial state is in the parallel state (mx = +1). The final state is back to P state (black curve) for 0.24 ns pulse and switches to AP state (red curve) for 0.19 ns pulse. The inset zooms into the magnetization evolution close to the moment at which the current pulse stops. (b) Switching probability as functions of pulse width and current density. Black-solid scatters represent no switching (the final P state) and red-open scatters denote switching (the final AP state). The red-curves are for guiding the view.
