Real-space observation of the low-temperature Skyrmion lattice in Cu2OSeO3(100) single crystal Open
Cu2OSeO3 is a skyrmion host material in which two distinct thermodynamically stable skyrmion phases were identified. We report magnetic force microscopy imaging of the low-temperature magnetic phases in bulk Cu2OSeO3(100) single crystal. T…

Short-wave magnons with multipole spin precession detected in the topological bands of a skyrmion lattice Open
Topological magnon bands enable uni-directional edge transport without backscattering, enhancing the robustness of magnonic circuits and providing a novel platform for exploring quantum transport phenomena. Magnetic skyrmion lattices, in p…

Origin of Subgap States in Normal-Insulator-Superconductor van der Waals Heterostructures Open
Superconductivity in van der Waals materials, such as NbSe2 and TaS2, is fundamentally novel due to the effects of dimensionality, crystal symmetries, and strong spin-orbit coupling. In this work, we perform tunnel spectroscopy on NbSe2 by…

Axial-Bonding-Driven Dimensionality Effect on the Charge-Density Wave in NbSe<sub>2</sub> Open
2H-NbSe2 is a prototypical charge-density-wave (CDW) system, exhibiting such a symmetry-breaking quantum ground state in its bulk and down to a single-atomic-layer limit. However, how this state depends on dimensionality and what governs t…
Spin-Reorientation-Driven Linear Magnetoelectric Effect in Topological Antiferromagnet Cu$_3$TeO$_6$ Open
The search for new materials for energy-efficient electronic devices has gained unprecedented importance. Among the various classes of magnetic materials driving this search are antiferromagnets, magnetoelectrics, and systems with topologi…

An entry from the Inorganic Crystal Structure Database, the world’s repository for inorganic crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely availabl…
Optically induced changes in the band structure of the Weyl charge-density-wave compound (TaSe4)2I Open
Collective modes are responsible for the emergence of novel quantum phases in topological materials. In the quasi-one dimensional (1D) Weyl semimetal , a charge density wave (CDW) opens band gaps at the Weyl points, thus turning the system…
Observation of the metallic mosaic phase in 1$T$-TaS$_2$ at equilibrium Open
The transition-metal dichalcogenide tantalum disulphide (1$T$-TaS$_2$) hosts a commensurate charge density wave (CCDW) at temperatures below 165~K where it also becomes insulating. The low temperature CCDW phase can be driven into a metast…

Soft-mode dynamics and sublattice polarization in an archetypal antiferroelectric Open
Terahertz and far-infrared techniques are combined with complementary Raman and inelastic neutron scattering results to probe the low-energy phonon dynamics of archetypal antiferroelectric candidate - francisite (Cu3Bi(SeO3)(2)O2Cl). The c…

Magnetic freeze-out and anomalous Hall effect in ZrTe$_5$ Open
The ultra-quantum limit is achieved when a magnetic field confines an electron gas in its lowest spin-polarised Landau level. Here we show that in this limit, electron doped ZrTe$_5$ shows a metal-insulator transition followed by a sign ch…

Influence of Dimensionality on the Charge Density Wave Phase of 2H‐TaSe<sub>2</sub> Open
Metallic transition metal dichalcogenides like tantalum diselenide (TaSe 2 ) exhibit exciting behaviors at low temperatures, including the emergence of charge density wave (CDW) states. In this work, density functional theory (DFT) is used…
Van der Waals pi Josephson junctions Open
Proximity-induced superconductivity in a ferromagnet can induce Cooper pairs with a finite center-of-mass momentum. The resultant spatially modulated superconducting order parameter is able to stabilize Josephson junctions (JJs) with pi ph…

Control of a polar order via magnetic field in a vector-chiral magnet Open
Vector-chiral (VC) antiferromagnetism is a spiral-like ordering of spins which may allow ferroelectricity to occur due to loss of space inversion symmetry. In this Letter we report direct experimental observation of ferroelectricity in the…
