Magnetic hopfions at room temperature
Kaixin Zhu, Wenli Gao, Zhan Wang +12
Hopfions are three-dimensional (3D) topological solitons predicted to exist in diverse magnetic systems, yet their practical utility has been largely restricted to cryogenic enviro…
Electrically steered conduction topologies and period-doubling phase dynamics in VO2
Siyuan Huang, Shuaishuai Sun, Yin Shi +6
The insulator-to-metal transition (IMT) in strongly correlated materials, such as vanadium dioxide (VO2), offers a transformative platform for next-generation adaptive electronics…
Ordering of Interstitial Iron Atoms and Local Structural Distortion Induced by Iron Polycomplex in Fe1+yTe1-xSex as Seen via Transmission Electron Microscopy

Xiao-Ping Ma, Ning-Ning Wang, Wen-Tao Wang +9
Structural investigations conducted using transmission electron microscopy (TEM) on LuH2 synthesized under atmospheric pressure (AP-LuH2) and nitrogen-doped LuH2 synthesized under…
Robust magnetism against pressure in non-superconducting samples prepared from lutetium foil and H2/N2 gas mixture
Jing Guo, Shu Cai, Dong Wang +15
Recently, the claim of "near-ambient superconductivity" in a N-doped lutetium hydride attracted enormous following-up investigations in the community of condensed matter physics an…
Photoinduced multistage phase transitions in Ta2NiSe5
Q. M. Liu, D. Wu, Z. A. Li +9
Utrafast control of material physical properties represents a rapid developing field in condensed matter physics. Yet, accessing to the long-lived photoinduced electronic states is…
Direct observations of chiral spin textures in van der Waals magnet Fe3GeTe2 nanolayers
Hong Wang, Cuixiang Wang, Yan Zhu +6
In two-dimensional van der Waals (vdW) magnets, the presence of magnetic orders, strong spin-orbit coupling and asymmetry at interfaces is the key ingredient for hosting chiral spi…
An Anomalous Circular Photogalvanic Effect in the Weyl Semimetal TaAs
Kai Sun, Shuaishuai Sun, Cong Guo +5
Weyl semimetal (WSM) is expected to be an ideal spintronic material owing to its spin currents carried by the bulk and surface states with spin-momentum locking. A photocurrent gen…
