Atomic-Scale Observation of Symmetry Breaking in Altermagnetic MnTe
Guodong Ren, Jonathan M. DeStefano, Xiao-Wei Zhang +20
The recent discovery of altermagnetism has sparked growing interest in compensated magnetic systems as promising platforms for highly scalable spintronics. Altermagnetism is a dist…
Three-Dimensional Atomic-Scale Structural Transformation in a SrTiO3 Grain Boundary
Xiaoyue Gao, Jiake Wei, Bo Han +9
Grain boundaries (GBs) in complex oxides play critical roles in governing their functional properties, which are intrinsically linked to their three-dimensional (3D) atomic configu…
Resolving Phonons in Superconductor Bi2Sr2CaCu2O8+δ at Sub-Unit-Cell Resolution
Xiaowen Zhang, Jiade Li, Xiaoyue Gao +9
The role of phonons in cuprates remains controversial, with their complex lattice structure complicating the investigation. Here, we identify phonon modes originating from charge r…
Precise structure and polarization determination of Hf0.5Zr0.5O2 with electron ptychography
Xiaoyue Gao1, Zhuohui Liu, Bo Han +8
Hf0.5Zr0.5O2 (HZO) is a promising candidate for next generation ferroelectric memories and transistors. However, its ferroelectricity origin is still under debate due to the comple…
