Observation of Fractionally Quantized Anomalous Hall Effect
Heonjoon Park, Jiaqi Cai, Eric Anderson +17
The integer quantum anomalous Hall (QAH) effect is a lattice analog of the quantum Hall effect at zero magnetic field. This striking transport phenomenon occurs in electronic syste…
Pseudogap behavior in charge density wave kagome material ScVSn revealed by magnetotransport measurements
Jonathan M. DeStefano, Elliott Rosenberg, Olivia Peek +5
Over the last few years, significant attention has been devoted to studying the kagome materials AVSb (A = K, Rb, Cs) due to their unconventional superconductivity and char…
Raman Study of Layered Breathing Kagome Lattice Semiconductor Nb3Cl8
Dylan A. Jeff, Favian Gonzalez, Kamal Harrison +11
Niobium chloride (Nb3Cl8) is a layered 2D semiconducting material with many exotic properties including a breathing kagome lattice, a topological flat band in its band structure, a…
Strain-programmable van der Waals magnetic tunnel junctions
John Cenker, Dmitry Ovchinnikov, Harvey Yang +12
The magnetic tunnel junction (MTJ) is a backbone device for spintronics. Realizing next generation energy efficient MTJs will require operating mechanisms beyond the standard means…
Controllable emergent spatial spin modulation in Sr2IrO4 by in situ shear strain
S. Pandey, H. Zhang, J. Yang +8
Symmetric anisotropic interaction can be ferromagnetic and antiferromagnetic at the same time but for different crystallographic axes. We show that inducing competition of anisotro…
Discovery of charge density wave in a correlated kagome lattice antiferromagnet
Xiaokun Teng, Lebing Chen, Feng Ye +18
A hallmark of strongly correlated quantum materials is the rich phase diagram resulting from competing and intertwined phases with nearly degenerate ground state energies. A well-k…
Anomalous Hall effect at half filling in twisted bilayer graphene

Magic-angle twisted bilayer graphene (tBLG) has been studied extensively owing to its wealth of symmetry-broken phases, correlated Chern insulators, orbital magnetism, and supercon…
Abrupt switching of the anomalous Hall effect by field-rotation in nonmagnetic ZrTe5
Joshua Mutch, Xuetao Ma, Chong Wang +7
The Hall effect arises when time reversal symmetry is broken by either intrinsic magnetism or an external magnetic field. The latter contribution dominates in non-magnetic material…

Qianni Jiang, Chong Wang, Paul Malinowski +10
The intrinsic antiferromagnetic topological insulator MnBiTe undergoes a metamagnetic transition in a c-axis magnetic field. It has been predicted that ferromagnetic Mn…
