A new material called “magnetic-charge ice” has been created by physicists in the US. The magnetic properties of the material can be manipulated at the nanometre scale and the material could someday be used to encode data at higher densities than current magnetic memories. The techniques used to create and control the new material could also lead to the realization of other artificial magnetic systems……
