Light-induced electronic polarization in antiferromagnetic Cr2O3
Xinshu Zhang, Tyler Carbin, Adrian B. Culver +5
In a solid, the electronic subsystem can exhibit incipient order with lower point group symmetry than the crystal lattice. External fields that couple to electronic order parameter…
Kibble-Zurek mechanism of Ising domains
Kai Du, Xiaochen Fang, Choongjae Won +5
The formation of topological defects after a symmetry-breaking phase transition is an overarching phenomenon that encodes rich information about the underlying dynamics. Kibble-Zur…
Topological Surface Magnetism and Neel Vector Control in a Magnetoelectric Antiferromagnet
Kai Du, Xianghan Xu, Choongjae Won +5
Antiferromagnetic states with no stray magnetic fields can enable high-density ultra-fast spintronic technologies. However, the detection and control of antiferromagnetic Neel vect…
Chiral Electronic Excitations in a Quasi-2D Rashba System BiTeI
A. C. Lee, B. Peng, K. Du +5
The optical transitions between spin-polarized bands of the quasi-two dimensional Rashba system BiTeI are investigated using polarization resolved resonant Raman spectroscopy. We d…
Highly tunable ferroelectricity in hybrid improper ferroelectric Sr3Sn2O7
Xianghan Xu, Yazhong Wang, Fei-Ting Huang +3
The successful theoretical prediction and experimental demonstration of hybrid improper ferroelectricity (HIF) provides a new pathway to couple octahedral rotations, ferroelectrici…
Microwave Conductivity of Ferroelectric Domains and Domain Walls in Hexagonal Rare-earth Ferrite
Xiaoyu Wu, Kai Du, Lu Zheng +3
We report the nanoscale electrical imaging results in hexagonal single crystals using conductive atomic force microscopy (C-AFM) and scanning microwave impe…
