Abstract

Utilizing the topological character of patterns in 3D structures is beneficial for information storage, magnetic memory and logic systems. One embodiment describes the use of topological knots, exemplified by a Möbius strip, in which a spin traversing along the band for a complete cycle will recover its original position, while having rotated away from its original orientation. The spins can respond to an external magnetic field, but cannot achieve a ferromagnetic state, in which all magnetic moments are pointing in the same direction, due to the topological knot. 3D assemblies of such nano-Möbius strips may form a prototype secure magnetic information storage device that are secure and with extremely low levels of energy dissipation.
