Field-coupled nanomagnets for interconnect-free nonvolatile computing

Exploiting the magnetic interaction of field-coupled single-domain magnets is promising for rad-hard, nonvolatile, dense and highly parallel digital information processing. The shortcomings of metal wiring are overcome as no current flow is needed for the logic operation. In principle only few k_BT energy per switching event are dissipated. Magnetic computing structures have been demonstrated before. Here electrical in- and output, magnetic signal branching and amplifier-like structures are fabricated, which will allow for complete computing systems operating at room temperature.
