Tiny magnets could work in sensors, information encoding

Scientists from Los Alamos National Laboratory, in collaboration with a group at the University of Illinois at Urbana-Champaign, the Lawrence Berkeley National Laboratory's Advanced Light Source and with other researchers nationwide, have realized a nanoscale, artificial magnet by arranging an array of magnetic nano-islands along a geometry that is not found in natural magnets. Their paper "Emergent reduced dimensionality by vertex frustration in artificial spin ice" appears on the journal Natur
