Dispersion Branch

It is shown that the dispersion characteristics of spin surface waves with dissipation unlike undamped waves have the wave number maximum value at which there is a reversal in the dispersion curve of wavenumber downward. This forms the upper branch of the dispersion curve with the inverse dispersion and high attenuation, which gives rise to ambiguous depending on the frequency of the wave vector. Lower primary dispersion branch corresponds to waves with a direct dispersion, attenuation is proportional to the small parameter of dissipation. However, near the wave number maximum value the attenuation coefficient of the waves sharply increases. Some angular and frequency limits of the of surface wave propagation are changed as well.

Surface Magnetostatic Wave

AbstractSpin-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.

AbstractWe have studied the properties of spin-wave excitations in a structure that is a junction of two regular magnon waveguides. The proposed structure enables the transmission of spin-wave signals in an irregular structure in the propagation mode of a surface magnetostatic wave. Using the method of micromagnetic simulation, the characteristics of the wave process have been calculated when changing the structure parameters, magnitude and direction of a magnetization field. It is shown that a system with translational symmetry violation can be used to transmit a signal in three-dimensional configurations of magnon networks.
