Purely Electric-Field Control of Topological Magnetism in Two-Dimensional Magnets
Zhonglin He, Naafis Ahnaf Shahed, Kai Huang +2
Electrical control of topological magnetism is central to realizing energy-efficient topological spintronics. Yet most electric-field approaches modify the competing magnetic inter…
Exchange Frustration and Topological Magnetism in Electrostatically Doped SrRuO3
Naafis Ahnaf Shahed, Himanshu Mavani, Zhonglin He +3
Magnetism in transition-metal systems emerges from exchange interactions that depend sensitively on carrier density. Yet leveraging this sensitivity to deliberately engineer exchan…
Competing Antiferromagnetic Phases in Multiferroic Wurtzite Transition-Metal Chalcogenides
Himanshu Mavani, Mohamed Elekhtiar, Kai Huang +2
Antiferromagnetic (AFM) spintronics offers a pathway toward electrically controllable spin-based devices beyond ferromagnets. Here, we identify wurtzite MnX (X = S, Se, Te) as a fa…
Two-dimensional antiferromagnets with non-relativistic spin splitting switchable by electric polarization
Himanshu Mavani, Kai Huang, Kartik Samanta +1
Spin-split antiferromagnets have significance for antiferromagnetic (AFM) spintronics due to their momentum dependent spin polarization which can be exploited for the control and d…
Prediction of polarization vortices, charge modulation, flat bands, and moiré magnetism in twisted oxide bilayers
Naafis Ahnaf Shahed, Kartik Samanta, Mohamed Elekhtiar +5
The recent surge of interest in moiré superlattices of twisted van der Waals compounds has spotlighted the emergence of unconventional superconductivity and novel electronic phases…
Two-dimensional non-volatile valley spin valve
Kai Huang, Kartik Samanta, Ding-Fu Shao +1
A spin valve represents a well-established device concept in magnetic memory technologies, whose functionality is determined by electron transmission being controlled by the relati…

Antiferroelectric Hafnia Down to the 2D Limit
Xin Li, Guodong Ren, Haidong Lu +16
Antiferroelectricity is a material property characterized by alternating electric dipoles spontaneously ordered in antiparallel directions. Antiferroelectrics are promising for ene…
Magnetic Antiskyrmions in Two-Dimensional van der Waals Magnets Engineered by Layer Stacking
Kai Huang, Edward Schwartz, Ding-Fu Shao +2
Magnetic skyrmions and antiskyrmions are topologically protected quasiparticles exhibiting a whirling spin texture in real space. Antiskyrmions offer some advantages over skyrmions…
Switchable anomalous Hall effects in polar-stacked 2D antiferromagnet MnBi2Te4
Tengfei Cao, Ding-Fu Shao, Kai Huang +2
Van der Waals (vdW) assembly allows controlling symmetry of two-dimensional (2D) materials that determines their physical properties. Especially interesting is the recently demonst…
Ferroelectric control of magnetic skyrmions in two-dimensional van der Waals heterostructures
Kai Huang, Ding-Fu Shao, Evgeny Y. Tsymbal
Magnetic skyrmions are chiral nanoscale spin textures which are usually induced by Dzyaloshinskii-Moriya interaction (DMI). Recently, magnetic skyrmions have been observed in two-d…
