摘要: We explore a new geometry allowing effective excitation of the lowest antisymmetric standing spin wave mode in ferromagnetic metallic films with symmetrical boundary conditions. The approach is based on use coplanar waveguide film, Permalloy (Py), playing role signal line. In addition, we study line which sandwich Py inside two nonmagnetic films. find that thickness and conductivity metal can significantly alter amount absorption, at resonance, between symmetric modes. experimental results are supported by numerical calculations indicating origin strength absorption.
