摘要

Dipole coupled nanomagnets controlled by the static Zeeman field can form various magnetic logic interconnects.However,the corner wire interconnect is often unreliable and error-prone at room temperature.In this study,we address this problem by making it into a reliable type with trapezoid-shaped nanomagnets,the shape anisotropy of which helps to offer the robustness.The building method of the proposed corner wire interconnect is discussed,and both its static and dynamic magnetization properties are investigated.Static micromagnetic simulation demonstrates that it can work correctly and reliably.Dynamic response results are reached by imposing an ac microwave field on the proposed corner wire.It is found that strong ferromagnetic resonance absorption appears at a low frequency.With the help of a very small ac field with the peak resonance frequency,the required static Zeeman field to switch the corner wire is significantly decreased by ～21 mT.This novel interconnect would pave the way for the realization of reliable and low power nanomagnetic logic circuits.
