Manipulating chiral-spin transport with ferroelectric polarization

ORAL

Abstract

Intense studies on spin transport in magnetic insulators have triggered renewed interest in magnon physics, and the potential use of magnons in energy-efficient electronics. Magnon flow in magnetic insulators, however, has thus far been manipulated primarily by magnetic fields that are expensive in energy. Here we report the experimental observation electric-field control of magnon transport in multiferroic BiFeO3, where the magnon transport is modulated in a non-volatile way by the ferroelectric polarization. The flow of magnons through a BiFeO3 layer changes by 18% at room temperature depending on the direction of the ferroelectric polarization, as measured by the inverse spin Hall technique. The spin torque borne by these magnons is furthermore sufficient to switch the magnetization of an adjacent ferromagnetic layer, with the critical switching current density similarly dependent on the ferroelectric polarization. Utilizing such a ferroelectrically controllable magnon transmission in BiFeO3, we propose an all oxide, energy-scalable logic that is composed of spin-orbit injection, detection, and magnetoelectric control.
