Observation of atomically displacive transformation out of the boundary-reconstructive phase competition
Qingqi Zeng, Zhiwei Du, Xiaolei Han +3
During the phase transitions, diverse states evolve with multiplex phenomena arising from the critical competition. In this study, a displacive martensitic transformation with a la…
Record-high Mobility and Extreme Magnetoresistance on Kagome-lattice in Compensated Semimetal Ni3In2S2
Hongwei Fang, Meng Lyu, Hao Su +14
The kagome-lattice crystal hosts various intriguing properties including the frustrated magnetism, charge order, topological state, superconductivity and correlated phenomena. To a…
Chiral Dirac fermion in a collinear antiferromagnet
Ao Zhang, Ke Deng, Jieming Sheng +18
In a Dirac semimetal, the massless Dirac fermion has zero chirality, leading to surface states connected adiabatically to a topologically trivial surface state as well as vanishing…
Scaling of Berry-curvature monopole dominated large linear positive magnetoresistance
Shen Zhang, Yibo Wang, Qingqi Zeng +15
The linear positive magnetoresistance (LPMR) is a widely observed phenomenon in topological materials, which is promising for potential applications on topological spintronics. How…
Pressure-Driven Magneto-Topological Phase Transition in a magnetic Weyl semimetal
Qingqi Zeng, Hongyi Sun, Jianlei Shen +9
The co-occurrence of phase transitions with local and global order parameters, such as the entangled magnetization and topological invariant, is attractive but has been seldom real…
On the anomalous low-resistance state and exceptional Hall component in hard-magnetic Weyl nanoflakes
Qingqi Zeng, Gangxu Gu, Gang Shi +7
Magnetic topological materials, which combine magnetism and topology, are expected to host emerging topological states and exotic quantum phenomena. In this study, with the aid of…
