Exploring new findings of interactions between electric fields and magnons is promising for novel magnonic applications\, which will allow f or efficient phase manipulation of magnon currents. Our team in Kaiserslau tern investigated the influence of a strong electric field on the phase\no f propagating spin waves in yttrium iron garnet (YIG) films. The experimen t was performed in different spin-wave excitation geometries when volume a nd surface magnetostatic spin waves were excited. With the help of a vecto r network analyzer\, the phase shift of the transmitted spin waves\, which is sensitive to different external influences\, was precisely measured. I n the first step\, by observing the electrically induced phase shifts of t he backward volume waves\, we determined the contribution of linear and qu adratic magnetoelectric effects for the used YIG film. Further\, the obtai ned magnetoelectric coefficients were used to approximate the phase shifts of the surface spin waves. It turned out that this approximation can be s uccessfully implemented only in the presence of an additional phase shift\ , which depends on the magnon wave number\, the spin-wave propagation path length\, and the electric field strength. This shift reached a value of 1 .2°\, comparable to the shift caused by the magnetoelectric effects. We i nterpret this additional phase shift as the influence of the magnon Aharon ov-Casher effect\, which consists of the geometrical accumulation of the p hase of spin waves as they pass through an electric field region.\n[1] P.
