Non-symmetric spin-pumping in a multiferroic heterostructure

Abstract : We present spin pumping experiments in Co/Pt bilayers, using surface acoustic waves to induce the magnetization precession. We show that the substrate on which the bilayer is deposited plays a role in the spin current excitation/detection processes. The electrical polarization of the substrate breaks the invariance for an inversion of both the magnetization vector and acoustic wave vector.
