Field-coupled nanomagnets for interconnect-free nonvolatile computing
MetadataShow full item record
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 kBT 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.
