论文摘要

我们通过微磁模拟证明了具有可调性手性的(反)手性的(反)天际的受控产生和an灭。通过在图案化的铁磁层中利用磁性(反)涡旋,我们以可复制的方式稳定了基本的Skyrmionic薄膜中(反)天空的完整晶格。 (反)天空的稳定性取决于(反)涡流的极化,而其手性是由(抗)涡流的旋转性给出的。此外,我们证明了(反)涡旋和(反)天际之间的核心耦合可以通过施加平面外部磁场的短脉冲来以受控的方式消灭旋转对象,从而代表Skyrmionic Decessices中的新键范式。

We demonstrate the controlled generation and annihilation of (anti)skyrmions with tunable chirality in magnetic heterostructures by means of micromagnetic simulations. By making use of magnetic (anti)vortices in patterned ferromagnetic layer, we stabilize full lattices of (anti)skyrmions in an underlying skyrmionic thin film in a reproducible manner. The stability of the (anti)skyrmion depends on the polarization of the (anti)vortex, whereas their chirality is given by those of the (anti)vortices. Furthermore, we demonstrate that the core coupling between the (anti)vortices and (anti)skyrmions allows to annihilate the spin-objects in a controlled fashion by applying short pulses of in-plane external magnetic fields, representing a new key paradigm in skyrmionic devices.
