论文摘要
实现有效的操纵和对拓扑自旋纹理的明确识别是两种至关重要的成分，可以使它们成为具有高存储密度，高数据处理速度和低能消耗的自旋设备中的信息载体。与传统法规相比，已经作为一种无耗散方法实现了对磁性的电场操作。但是，磁化强度通常对电场不敏感，因为它不会直接打破时间反转对称性，并且由于外部波动引起的漂移，拓扑磁准粒子的分布很难维持，这可能会导致二颗粒和均匀磁性背景之间的含糊不清。在这里，我们证明了电动极化驱动的高气压和统一的铁磁状态，可以轻松，明确地通过在基于Janus磁铁的多型异质结构LACLBR/IN2SE3中由异常的Valley Hall效应产生的横向电压来区分。我们的工作为数据编码提供了另一种方法，其中通过将拓扑旋转纹理与可检测到的电子传输梳理来编码数据。
Realizing effective manipulation and explicit identification of topological spin textures are two crucial ingredients to make them as information carrier in spintronic devices with high storage density, high data handling speed and low energy consumption. Electric-field manipulation of magnetism has been achieved as a dissipationless method compared with traditional regulations. However, the magnetization is normally insensitive to the electric field since it does not break time-reversal symmetry directly, and distribution of topological magnetic quasiparticles is difficult to maintain due to the drift arising from external fluctuation, which could result in ambiguous recognition between quasiparticles and uniform magnetic background. Here, we demonstrate that electric polarization-driven skyrmionic and uniform ferromagnetic states can be easily and explicitly distinguished by transverse voltage arising from anomalous valley Hall effect in the Janus magnet-based multiferroic heterostructure LaClBr/In2Se3. Our work provides an alternative approach for data encoding, in which data are encoded by combing topological spin textures with detectable electronic transport.
