Abstract
- Current driven magnetization switching dynamics induced by spin-transfer torque in CoPt/Au/CoPt nanopillar device with interface anisotropy is investigated by solving the Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation numerically. The switching of magnetization in the free layer CoPt/Au/CoPt nanopillar with a thickness of 3 nm occurs above the threshold current density of 0.84×108A/cm2. This reduces to 0.30×108A/cm2 when the free CoPt layer of the device has interface anisotropy in it. The presence of interface anisotropy also reduces the magnetization switching time from 8.4 ps to 3.1 ps when the device is operated by a current with a density of 2.78×108A/cm2.
