Perpendicular standing spin wave
WebSpin waves exist even in electrically insulating magnets, where they are able to propagate inherently free of the dissipative motion of charge. They can have nanometer wavelengths and gigahertz frequencies well suited for chip-scale device technologies and interference-based spin-wave logic circuits ( 2 ). WebMar 1, 2024 · Perpendicular standing spin waves formed in the thickness direction of the magnetic film are a typical case. However, the dimensions in both the thickness direction and the width direction are limited in uniform strip waveguides.
