Interface-Induced Stability of Nontrivial Topological Spin Textures: Unveiling Room-Temperature Hopfions and Skyrmions
F. Katmis, V. Lauter, R. Yagan +9
Topological spin configurations, such as soliton-like spin texture and Dirac electron assemblies, have emerged in recent years in both fundamental science and technological applica…
Sensing the local magnetic environment through optically active defects in a layered magnetic semiconductor
Julian Klein, Zhigang Song, Benjamin Pingault +14
Atomic-level defects in van der Waals (vdW) materials are essential building blocks for quantum technologies and quantum sensing applications. The layered magnetic semiconductor Cr…
Progress and prospects in the quantum anomalous Hall effect
Hang Chi, Jagadeesh S. Moodera
The quantum anomalous Hall effect refers to the quantization of Hall effect in the absence of applied magnetic field. The quantum anomalous Hall effect is of topological nature and…
A van der Waals Interface Hosting Two Groups of Magnetic Skyrmions
Yingying Wu, Brian Francisco, Wei Wang +9
Multiple magnetic skyrmion phases add an additional degree of freedom for skyrmion based ultrahigh-density spin memory devices. Extending the field to two-dimensional van der Waals…
Unconventional Planar Hall Effect in Exchange-Coupled Topological Insulator-Ferromagnetic Insulator Heterostructures
David Rakhmilevich, Fei Wang, Weiwei Zhao +4
The Dirac electrons occupying the surface states (SSs) of topological insulators (TIs) have been predicted to exhibit many exciting magneto-transport phenomena. Here we report on t…
Signatures of long-range-correlated disorder in the magnetotransport of ultrathin topological insulators
D. Nandi, B. Skinner, G. H. Lee +10
In an ultrathin topological insulator (TI) film, a hybridization gap opens in the TI surface states, and the system is expected to become either a trivial insulator or a quantum sp…
