Abstract

Spin waves in chains of magnetic particles shaped as elongated ellipsoids magnetized along the chain axis have been studied. The dispersion relation of such waves were found and the edges of the magnonic transmittance band have been analytically derived. It is shown that edge modes appear at the ends of a chain, and their existence is caused by static stray fields attenuating at the ends of the chains.

非球形磁性粒子链中的磁振子和边缘模式

摘要

已经研究了形状为细长椭圆形的磁性粒子链沿链轴磁化的自旋波。发现了此类波的色散关系，并已解析得出了镁磁传输带的边缘。结果表明，边缘模式出现在链的末端，其存在是由于静态杂散场在链的末端衰减而引起的。
