Abstrakt

Controlling the phase and amplitude of spin waves in magnetic insulators with an electric field opens the way to fast logic circuits with ultralow power consumption. One way to achieve such control is to manipulate the magnetization of the medium via magnetoelectric effects. In experiments with magnetostatic spin waves in an yttrium iron garnet film, we have obtained evidence of a theoretically predicted phenomenon: the change of the spin-wave phase due to the magnonic Aharonov-Casher effect - the geometric accumulation of the magnon phase as these quasiparticles propagate through an electric field region.
