Abstract

The invention discloses a modulation method for spin waves in a self-bias magnetic oscillator waveguide, which is used for modulation a propagation behavior of the spin waves in the waveguide, wherein the propagation behavior comprises the maximum propagation frequency, the cut-off frequency and the propagation path of the spin waves. The modulation method comprises the steps of adjusting the maximum propagation frequency at which the spin waves can be constrained in a middle channel of the waveguide; adjusting the cut-off frequency of the spin waves in channels at two sides of the waveguide; and adjusting the propagation path of the spin waves. According to the invention, modulation can be performed on the propagation behavior of the spin waves on the switched elastic magnetic structure based magnetic oscillator waveguide.

Description

technical field [0001] The invention relates to the technical field of magnon devices, in particular to a method for modulating spin waves in a self-biased magnon waveguide. Background technique [0002] In 1930, the Swiss physicist Bloch first proposed the concept of spin wave - the collective motion of the magnetic moments interacting (mainly exchange and dipole interactions) in magnetically ordered bodies due to excitation . Holstein T and Primakoff H quantized it and called it a magnon. In recent years, with the in-depth study of magnetism and electron spin characteristics, many excellent properties of spin waves have been discovered one after another. The design and manufacture of magnon devices with spin waves as information carriers has become a "post-CMOS era". "One of the directions with great development prospects. [0003] The traditional semiconductor integrated circuit technology uses carriers (electrons or holes) as the carrier of information transmission, a...
