Strain mediated Bennett clocking has only recently been experimentally demonstrated and suffered from high error rates. Most models used to explain this behavior are macrospin models. Predictions of these models do not match experimental designs since they consider all spins rotating coherently and no magnetoelastic strain feedback. In this paper a fully coupled nonlinear model (LLG plus elastodynamics) was used to simulate voltage induced Bennett clocking. This modelling captures the full spin dynamics as well as shape anisotropy. Two materials were studied (Ni and Terfenol-D) which have very different exchange lengths. The simulation results show that incoherent rotation may occur due to the uniaxial nature of the magnetoelastic coupling. |
