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…
High bosonic Bott index and transport of multi-band topological magnons
Kai Tao Huang, X. S Wang
Magnons are bosonic quasiparticles in magnetically ordered systems. Bosonic Bott index has been affirmed as a real-space topological invariant for a two-band ferromagnetic model. I…
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…
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…
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 phase…
