Bringing Artificial Spin Ice Closer to Application (1 of 7)

Caption

This is a depiction of magnetic charge ice. Nanoscale magnets are arranged in a two-dimensional lattice. Each nanomagnet produces a pair of magnetic charges, one positive (red ball on the north pole) and one negative (blue ball on the south pole). The magnetic flux lines (white) point from positive charges to negative charges. This material relates to a paper that appeared in the May 20, 2016 issue of Science, published by AAAS. The paper, by Y.-L. Wang at Argonne National Laboratory in Argonne, IL, and colleagues was titled, "Rewritable artificial magnetic charge ice."
