自旋波在具有磁弹性的受限铁磁条形线中长距离传播，为器件应用开辟了广阔的前景。畴壁作为自旋波的天然通道，增加了自旋波的传播距离。我们通过微磁模拟和含有nsamel壁的条形线的色散关系计算了磁模和弹性模。我们发现在色散关系的交叉点处，观察到两种行为：当存在强耦合时出现反交叉间隙，或者当磁弹性反馈循环不满足时出现无间隙点。对于nsamel壁限磁模，磁波和弹性波独立振荡形成一个无间隙交叉点。对于域模式，可以找到这两种行为。我们基于本征模的对称性讨论了间隙的存在性。
Spin wave propagation over long distances in confined ferromagnetic strip lines exhibiting magnetoelasticity opens up promising perspectives for device applications. Domain walls as natural spin wave channels increase the spin wave propagation distance. We calculate the magnetic and elastic modes through micromagnetic simulations and the dispersion relation of strip lines containing a Néel wall. We show that at the crossing points in the dispersion relation, two behaviors are observed: an anticrossing gap when a strong coupling is present or a gapless point when the magnetoelastic feedback cycle is not fulfilled. For the Néel wall-confined magnetic mode, the magnetic and elastic waves oscillate independently forming a gapless crossing point. For the domain modes, both behaviors are found. We discuss the gap existence based on the symmetry of the eigenmodes.
