摘要：
The effect of biquadratic coupling on spin transfer torque-assisted magnetization switching in the pentalayer nanopillar device is studied by numerically solving the magnetization switching dynamics of the free layer governed by the Landau- Lifshitz-Gilbert-Slonczewski (LLGS) equation. Magnetization switching time in the absence of biquadratic coupling for an applied current density of 10 × 1011Am− 2 is 186 ps. Biquadratic coupling arises due to the uncorrelated roughness in the ferromagnetic layers and it reduces the switching time to 160 ps. Further, the impact of the period of roughness and spacer layer thickness on switching time are studied.
