Non-uniform magnetic domains with non-trivial topology, such as vortices and
skyrmions, are proposed as superior state variables for nonvolatile information
storage. So far, the possibility of logic operations using topological objects
has not been considered. Here, we demonstrate numerically that the topology of
the system plays a significant role for its dynamics, using the example of
vortex-antivortex pairs in a planar ferromagnetic film. Utilising the dynamical
properties and geometrical confinement, direct logic communication between the
topological memory carriers is realised. This way, no additional
magnetic-to-electrical conversion is required. More importantly, the information
carriers can spontaneously travel up to ~300 nm, for which no spin-polarised
current is required. The derived logic scheme enables topological spintronics,
which can be integrated into large-scale memory and logic networks capable of
complex computations.
