Magnetic memory and current amplification devices using moving domain walls
S. E. Barnes, J. Ieda, S. Maekawa
Abstract
A moving magnetic domain wall produces an electromotive force (emf). It is therefore possible to read the state of a magnetic memory device via the emf it produces when subject to an interrogation pulse. It is also possible to amplify currents in pulse circuits, opening up the possibility of all magnetic logic circuits.
