    Spin waves in CoFeB on ferroelectric domains combining spin mechanics and magnonics
    (Elsevier BV, 2014) Brandl, F.; Franke, K.J.A.; Lahtinen, T.H.E.; van Dijken, S.; Grundler, D.; Teknillisen fysiikan laitos; Department of Applied Physics; Perustieteiden korkeakoulu; School of Science
    Spin dynamics controlled by magnetoelastic coupling and applied electric fields might play a vital role in future developments of magnonics, i.e., the exploitation of spin waves for the transmission and processing of information. We have performed broadband spin-wave spectroscopy on a magnetostrictive CoFeB alloy grown on a ferroelectric BaTiO3 substrate causing elastic strain with a quasi-periodic modulation. We find characteristic eigenfrequencies and spin-wave modes with large group velocities and small damping. These results suggest bright perspectives for electric-field control of reprogrammable magnonics.
