Dynamics of current-driven interacting magnetic domain walls

我们研究了电流驱动的磁存储器件中的铁磁畴壁的动力学。畴壁被用作磁存储信息的基本元件。为了实现磁性纳米结构的最大密集堆积以最大化信息密度（并因此小型化），磁性纹理的相互作用是不可避免的。我们打算计算出畴壁与电流驱动的伙伴的磁耦合的影响，以揭示其动力学性质。我们的研究结果可以预期，以促进了解如何磁器件必须进行优化，以避免不希望的影响，或探索最佳的磁信息处理的相互耦合。

We study the dynamics of current-driven ferromagnetic domain walls in densely packed magnetic storage devices. Domain walls are used as basic elements of magnetically stored information. Aiming to achieve a maximally dense packing of magnetic nanostructures in order maximize information density (and thus miniaturization), a mutual interaction of the magnetic textures is unavoidable. We intend to work out the impact of a magnetic coupling of a domain wall to a current-driven partner in order to reveal its dynamical properties. Our results can be expected to advance the understanding of how magnetic devices have to be optimized to either avoid undesired effects or to explore mutual coupling for optimal magnetic information processing.
