任意方向界面外磁场下侧向金属磁性超晶格

MAGNETOSTATIC MODES OF LATERAL METAL MAGNETIC SUPERLATTICES FOR AN ARBITRARY EXTERNAL FIELD APPLIED PARALLEL TO THE SURFACE

我们研究了侧向金属磁性超晶格的静磁模 .我们考虑外磁场位于界面内并可沿任意方向 ,自旋波沿垂直磁化强度的方向传播 ,衰减是来自于涡流 .一些有意义的性质被发现 ,比如频率是衰减不仅与电导率、波数有关 ,而且与外磁场方向。

We investigate magnetostatic modes of lateral magnetic superlattices composed of metallic magnetic layers and insulating nonmagnetic layers.We assume that the in-plane waves always propagate normal to the static magnetization for an arbitrary external field applied parallel to the surface,and that the damping results from eddy currents.Some interesting properties are found,for example,these features of the frequency and damping are not only governed by the conductivity and wave number,but also by the direction and magnitude of external magnetic field.
