Controlling the Properties of Spin–Wave Transport in a Semiring Magnon Microwavevguide

Аннотация

Spin-wave transport along a waveguide structure with disturbed translational symmetry has been investigated. A semiring portion of a magnon microwaveguide has been made of a YIG film. It has been shown that one can control the dynamic magnetization spatial distribution by varying the magnetic biasing angle in the microwaveguide plane. Under such conditions, the transmission coefficient of standing waves changes noticeably. The structure suggested in this paper allows the rotation of spin-wave signals in an irregular configuration under the conditions of surface magnetostatic wave propagation. This effect may be used in planar magnon networks.
