Spin waves in insulating magnets are ideal carriers for spin currents with low energy dissipation. An electric field can modify the dispersion of waves, by directly affecting, via spin-orbit coupling, electrons that mediate interaction between magnetic ions. Our microscopic calculations based on super-exchange model indicate this effect is sufficiently large to be used effectively control currents. We apply these findings design a spin-wave interferometric device, which acts as logic...
