Abstract

Nanomagnetic logic transmits information along a path of nanomagnets which have to be reset to receive efficiently information from their neighbor. Such a process, known as clocking, can be designed by exploiting spin-Hall effect (SHE), as recently observed in experiments on a Ta/CoFeB/MgO device. We have performed a full micromagnetic analysis of two devices, the first is used to compare our results with the experiments, the second predicts the influence of the Dzyaloshinskii-Moriya interaction (DMI) on the clocking process. Our achievements show that SHE-driven clocking is a non-uniform state. The observed configurations are Bloch domain walls in absence of DMI, Neél domain walls with DMI included.
