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…
Anomalous charge density wave in a two-dimensional superatomic superconductor
Boqin Song, Shuaishuai Sun, Zhongxu Wei +12
The spatial modulation of electron density into a wave-like pattern, known as charge density wave (CDW), represents a fundamental quantum state that often coexists with superconduc…
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, Lu Zhang, Wen-Tao Wang +8
Employing aberration-corrected scanning transmission electron microscopy (STEM), we meticulously investigated the intrinsic chemical heterogeneity of Fe1+yTe, Fe1+yTe0.8Se0.2, and…
