标题： Bimerons as Edge states in Thin Magnetic Strips

摘要： 磁双子是自旋电子器件中的潜在信息载体。 双子在具有面内磁化的手性磁系统中表现出来，由于各向异性或外部磁场而与磁子拓扑等价。 需要其电流驱动运动的应用面临重大挑战，尤其是双子霍尔效应，这会导致在纳米磁边界处的横向运动和湮灭。 本研究解决了在电流驱动条件下稳定双子传播的问题。 我们证明，当易轴各向异性和电流相互垂直时，双子可以在薄铁磁条中传播而不发生湮灭。 我们的研究结果表明，在电流的一个阈值以下，双子与条带边界之间的排斥作用允许稳定的孤子传播，即使在弯曲区域也是如此。 这种现象也适用于双子链，它们沿着电流流动方向传播。 通过实现稳定的长距离传播，我们的结果为开发基于双子的磁道存储设备开辟了新途径，提高了未来自旋电子应用的效率和可靠性。 显示英文摘要

摘要： Magnetic bimerons are potential information carriers in spintronic devices. Bimerons, topologically equivalent to skyrmions, manifest in chiral magnetic systems with in-plane magnetization due to anisotropies or external magnetic fields. Applications demanding their current-driven motion face significant challenges, notably the bimeron Hall effect, which causes transverse movement and annihilation at nanomagnet borders. This study addresses the problem of stabilizing bimeron propagation under current-driven conditions. We demonstrate that bimerons can propagate through thin ferromagnetic strips without annihilation when the easy-axis anisotropy and the electric current are orthogonal. Our findings indicate that below a threshold value of current, the repulsion between the bimeron and the strip boundary allows for stable soliton propagation, even in bent regions. This phenomenon extends to bimeron chains, which propagate parallel to the current flow. By enabling stable long-distance propagation, our results open new avenues for developing bimeron-based racetrack memory devices, enhancing the efficiency and reliability of future spintronic applications.
