论文摘要
我们报告了使用微磁模拟的刺激性铁磁纳米弹力中的自旋转移扭矩驱动的气泡动力学。在质量小于1的三维单轴铁磁铁中，Skyrmion气泡被从几何形状边界的排斥力被迫停留在中央纳米条上。可以通过将质量因子提高到〜3.8来实现纳米条中Skyrmion气泡的相干运动。我们的结果应推动基于偶极稳定的Skyrmion气泡等未来的Spintronic设备的设计，例如人工神经计算和赛马场记忆。
We report dynamics of skyrmion bubbles driven by spin-transfer torque in achiral ferromagnetic nanostripes using micromagnetic simulations. In a three-dimensional uniaxial ferromagnet with a quality factor that is smaller than 1, the skyrmion bubble is forced to stay at the central nanostripe by a repulsive force from the geometry border. The coherent motion of skyrmion bubbles in the nanostripe can be realized by increasing the quality factor to ~3.8. Our results should propel the design for future spintronic devices such as artificial neural computing and racetrack memory based on dipole-stabilized skyrmion bubbles.
