Logic device based on spin wave interference and multiferroic material

Abstract

The invention discloses a logic device based on spin wave interference and a multiferroic material. The logic device comprises five functional zones, namely, a spin wave excitation zone, a spin wave frequency division zone, an electric field regulation and control zone, a spin wave interference zone, and a spin wave detection zone; the basic structure and shape of the logic device are achieved through a spin wave transmission medium; due to the dispersion relation of spin waves in the medium, the spin wave transmission direction and model change in case of an external magnetic field or an internal magnetism change of the medium. The logic device provided by the invention can be used for achieving information transmission and logic operation; the spin waves are based on electron spin, and a regulation and control voltage is based on an electric field, so that electron generation or hole movements are eliminated, and the joule heat produced by electric current and the problem of quiescent dissipation due to leak current are effectively avoided.

technical field [0001] The invention relates to the structural design and functional application of a logic device based on spin wave interference involving multiferroic materials, and belongs to the basic electrical components in the electrical field. Background technique [0002] Traditional semiconductor-based storage and computing technologies, with the increase in integration and the miniaturization of electronic devices, the heat loss inside the device due to current Joule heat has risen sharply, and the static power consumption caused by the quantum tunneling effect accounts for The proportion is increasing exponentially, and it has increasingly become a key factor restricting traditional storage and logic devices. [0003] Spin Wave, or Magnon, refers to the eigenmode of the collective vibration of electron spins in magnetically ordered materials (such as ferromagnetic, ferrimagnetic, antiferromagnetic materials). The logic device based on spin wave propagation is a...
