Dual function spin-wave logic gates based on electric field control magnetic anisotropy boundary

Abstract

Spin waves (SWs) have been considered a promising candidate for encoding information with lower power consumption. Here, we propose dual function SW logic gates, one unit cell with two synchronized logic operation functions, based on the electric field controlling of the SW propagation in the Fe film of a Fe/BaTiO3 heterostructure by the motion of a magnetic anisotropy boundary. We show micromagnetic simulations to validate the and–or and nand–nor logic gates. Our research may find a path for simplifying integrated logic circuits using such dual function SW logic gates.
