Information industry is one of the major drivers of the world economy. Its rapid growth, however, leads to severe heat problem which strongly hinders further development. This calls for a non-charge-based technology. Magnon, capable of transmitting spin information without electron movement, holds tremendous potential in post-Moore era. Given the cornerstone role of the field effect transistor in modern electronics, creating its magnonic equivalent is highly desired but remains a challenge. Here, we demonstrate a nonvolatile three-terminal lateral magnon field effect transistor operating at room temperature. The device consists of a ferrimagnetic insulator (YFeO) deposited on a ferroelectric material [Pb(MgNb)TiO or Pb(ZrTi)O], with three Pt stripes patterned on YFeO as the injector, gate, and detector, respectively. The magnon transport in YFeO can be regulated by the gate voltage pulses in a nonvolatile manner with a high on/off ratio. Our findings provide a solid foundation for designing energy-efficient magnon-based devices.
信息产业是世界经济的主要驱动力之一。然而，其快速发展导致了严重的发热问题，这极大地阻碍了进一步发展。这就需要一种非电荷型技术。磁振子能够在不发生电子移动的情况下传输自旋信息，在摩尔时代之后具有巨大潜力。鉴于场效应晶体管在现代电子学中的基石作用，制造其磁振子等效物是非常必要的，但仍然是一个挑战。在此，我们展示了一种在室温下工作的非易失性三端横向磁振子场效应晶体管。该器件由沉积在铁电材料[Pb(MgNb)TiO或Pb(ZrTi)O]上的亚铁磁绝缘体(YFeO)组成，在YFeO上图案化有三条Pt条带，分别作为注入器、栅极和探测器。YFeO中的磁振子传输可以通过栅极电压脉冲以非易失性方式进行调节，具有很高的开/关比。我们的发现为设计节能型磁振子基器件提供了坚实的基础。
