1. A method for achieving specific states of functionally coupled islands of a functional material, said functionally coupled island being placed within a chirality-controlled kagome spin ice structure, each ring structure having six islands with their long axis at 120°

  • to their neighbors and created, for example, by lithographic means;

    each of the functionally coupled islands being oriented along one of the six sides of the hexagonal ring structure of said kagome spin ice component, wherein the functionally coupled islands are substantially identical but differ in a given physical property;

    said functionally coupled island structures providing a mechanism in which the energy state and vortex chirality is controlled according to the physical property of the functional material in the functionally coupled islands.
