Spin waves transport in 3D magnonic waveguides

Abstract

In this work, the propagation of spin waves in translational symmetry broken irregular magnonic waveguide is investigated. The mechanism of the transfer of the magnetic moment and the conversion of spin waves from backward volume to surface waves is revealed. Mechanisms for controlling spin-wave transport by changing the direction of an external magnetic field are investigated by the method of micromagnetic modeling. The results of studies of structures with broken translational symmetry open up new possibilities for the formation of multilayer magnonic networks of various topologies and miniaturization of computing devices based on the principles of magnonics.
