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 [1]. Magnetic computing structures have been demonstrated before [2-4]. 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. In Fig. 28.4.1 we sketch a programmable logic gate with integrated in- and output structures. The basic building blocks are nanodots comprised of a collective system of ferromagnetically aligned spins with the preferred axis normal to the film-plane. These up- and down-states represent the Boolean ‘0’
