Transition-metal-based kagome materials at van Hove filling are a rich frontier for the investigation of novel topological electronic states and correlated phenomena. To date, in idealized two-dimensional lattice, topologically Dirac surface (TDSSs) have not been unambiguously observed, manipulation TDSSs singularities (VHSs) remains largely unexplored. Here, we reveal originating from ℤ2 bulk topology identify multiple VHSs near Fermi level (EF) magnetic material GdV6Sn6. Using situ...
The application of optimal electron count has proven effective in predicting the existence complex structural topologies containing electron-rich polyanionic networks, including linear and zig-zag chains, square planar structures, simple cubic lattices main group elements. In this study, we report successful synthesis a new family magnetic compounds, RSe2−x (x ∼ 1/6) (R = Gd Tb), using KCl flux. resulting crystal structure is tetragonal, exhibiting PbFCl-type symmetry with space P4/nmm....
Magnetic structure and crystal symmetry, which primarily determine the time-reversal inversion may give rise to numerous exotic quantum phenomena in magnetic semiconductors semimetals when arranged different patterns. In this work, a new layered semiconductor, Eu3−δZnxSnyAs3, was discovered high-quality single crystals were grown using Sn flux. According structural characterization by x-ray diffraction atomic-resolution scanning transmission electron microscopy, Eu3−δZnxSnyAs3 is found...
A new compound, Ba3Ga2O5Cl2, isostructural with Ba3Fe2O5Cl2, was synthesized by solid-state reaction in air. Through single-crystal and powder X-ray diffraction analysis, the crystal structure determined to be cubic chiral space group I213 unit-cell parameter a = 9.928 (1) Å. The Ga3+ ions Ba3Ga2O5Cl2 are coordinated O atoms form GaO4 tetrahedra. Ten neighboring tetrahedra further bridged through corner sharing rotation along body diagonal, producing structure. Magnetization measurements...
In this study, a novel magnetic semimetal compound, Gd8Mn3Sb19, was synthesized successfully via high-temperature solid-state reaction. The crystal structure of Gd8Mn3Sb19 determined using both single and powder X-ray diffraction techniques, revealing non-centrosymmetric orthorhombic space group, Pmn21 (No. 31). Sb atoms in form five-atom-wide Sb57− ribbons, narrower three-atom-wide Sb35− Sb3- anions. On the other hand, Gd3+ Mn2+ ions distorted Gd3 Mn3 triangular lattices, respectively....
