Dimensional crossover and local strain induced deflection of the spin spiral state in multiferroic NiI2
Tianxing Jiang, Lianchuang Li, Haiyan Zhu +10
Low-dimensional multiferroics hold great promise for integrated magnetoelectric devices. Spin spiral state has recently been shown to induce ferroelectricity in single-layer van de…
Direct observation of interfacial exchange coupling in a magnetic tunnel junction through spin-polarized quasiparticle interference
Xu Wang, Chenxi Wang, Ying Yang +5
Interfacial exchange coupling plays a critical role in enabling novel phenomena in magnetic heterostructures, such as spin triplet superconductivity, quantum anomalous Hall effect…
Microscopic evidence of spin-driven multiferroicity and topological spin textures in monolayer NiI2
Haitao Wang, Tianxing Jiang, Weiyi Pan +12
In type II multiferroics, noncollinear spin textures are expected to induce electric polarization directly, leading to strong magnetoelectric coupling. Realizing such spin driven m…
Revealing Higher-Order Topological Bulk-boundary Correspondence in Bismuth Crystal with Spin-helical Hinge State Loop and Proximity Superconductivity
D. M. Zhao, Y. Zhong, T. Yuan +7
Topological materials are typically characterized by gapless boundary states originated from nontrivial bulk band topology, known as topological bulk-boundary correspondence. Recen…
Discovery of Itinerant Magnetic Domain Wall and Quasiparticle Boundary State in Spin-Density-Waves
Yining Hu, Xu Wang, Chen Chen +7
Conventional magnetic domain walls are characterized by reorientation of local spins. However, what occurs at the boundary of itinerant magnets is largely unknown. Here using spin-…
