Multiferroic VHfO with Strain-Tunable Magnetism
Qisheng Yu, Tianyuan Zhu, Boyu Liu +2
The coexistence of ferroelectricity and magnetism in a single-phase oxide is rare because the electronic requirements for these two orders are often incompatible. Here, using first…
Atomistic Structure of Transient Switching States in Ferroelectric AlScN
Jiawei Huang, Jinyang Li, Xinyue Guo +5
We resolve the microscopic mechanism of polarization switching in wurtzite ferroelectric AlScN by integrating advanced thin-film fabrication, ferroelectric switching dynamics chara…
Unraveling Shear Strain Induced Ferroelectric-to-Antiferroelectric Phase Transition and Accessing Intrinsic Antiferroelectricity in Two-dimensional NbOCl2
Jiawei Mao, Yinglu Jia, Gaoyang Gou +2
Compared to the well studied two-dimensional (2D) ferroelectricity, much rare is the appearance of 2D antiferroelectricity, where local dipoles from the nonequivalent sublattices w…
Bonding relay for room-temperature oxide plasticity like metals
Xiangkai Chen, Yuhong Li, Xiaofei Zhu +2
Oxides have long been regarded as intrinsically brittle due to their strong, directional ionic or covalent bonds, in stark contrast to the ductile behavior of metals, where delocal…
