We demonstrate the functionality of spin-wave logic exclusive-not-OR and not-AND gates based on a Mach-Zehnder-type interferometer which has arms implemented as sections of ferrite film spin-wave waveguides. Logical input signals are applied to the gates by varying either the phase or the amplitude of the spin waves in the interferometer arms. This phase or amplitude variation is produced by Oersted fields of dc current pulses through conductors placed on the surface of the magnetic films.

Transmission of electrical signals by spin-wave interconversion in a magnetic insulator (2010, background): “For instance, in the magnetic insulator Y 3 Fe 5 O 12 , the spin-wave decay length can be several centimetres 3 and thus the waves are propagated over a relatively long distance; Y 3 Fe 5 O 12 is an ideal conductor for spin-wave spin currents even though it is an insulator for electric currents.”
Magnonic logic circuits (2010, background): “In the experimentally realized prototype devices [7, 8, 11], the operating wavelength was of the order of several micrometres.”
