Previously unreported High-Entropy Alloy (HEA) superconductors in the pentanary (ZrNb)<sub>1−x</sub>[MoReRu]<sub>x</sub>, (HfTaWIr)<sub>1−x</sub>[Re]<sub>x</sub>, and (HfTaWPt)<sub>1−x</sub>[Re]<sub>x</sub> systems are described characterized.
We report the magnetic properties of compounds in KBaRE(BO3)2 family (RE = Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb), materials with a planar triangular lattice composed rare earth ions. The samples were analyzed by x-ray diffraction and crystallize space group R-3m. Physical property measurements indicate display predominantly antiferromagnetic interactions between spins without any signs ordering above 1.8 K. ideal 2D layers this structure type make it potential model system for investigating...
Edge supercurrents in superconductors have long been an elusive target. Interest them has reappeared the context of topological superconductivity. We report evidence for existence a robust edge supercurrent Weyl superconductor molybdenum ditelluride (MoTe2). In magnetic field B, fluxoid quantization generates periodic modulation condensate observable as "fast-mode" oscillation critical current Ic versus B The fast-mode frequency is distinct from conventional Fraunhofer displayed by bulk...
A previously unreported family of electrically insulating rare-earth borates, RbBaR(BO3)2 (R = Y, Gd–Yb), was designed and then successfully obtained by traditional solid-state reaction. They crystallize in a monoclinic crystal system space group P21/m (No. 11). feature triangular planar (R) lattices, which are part of, for example, [Yb(BO3)2]3– infinite 2D layers. These R-based lattices stacked with layers crystallographically ordered Rb Ba atoms to build the 3D structures. Polycrystalline...
The growth of single crystals MoS2 and WS2 by materials transport through a liquid salt flux made from low-melting mixture NaCl CsCl is presented. are structurally characterized single-crystal X-ray diffraction, which reveals that the 2H-MoS2 contain very small percentage (about 3%) 3R intergrowths 2H-WS2 display less than 1% intergrowths. Characterization scanning electron microscopy presented as photoluminescence spectra exfoliated monolayers show grown this method superior in quality to...
The synthesis, structural description, temperature dependent magnetic susceptibilities and field magnetizations of a series rare earth garnets the form Li3RE3Te2O12 (RE = Y, La, Pr, Nd, Sm-Lu) are reported. structure Li3Dy3Te2O12 is refined from powder x-ray diffraction data. saturate for some members by 9 Tesla at 2 K. Of particular interest further study in this family behavior Tb, Dy Yb garnets.

The crystal growth, structure, and basic magnetic properties of TmMgGaO4 are reported. Tm ions located in a planar triangular lattice consisting distorted TmO6 octahedra, while the Mg Ga atoms randomly occupy intermediary bilayers M-O bipyramids. positionally disordered. material displays an antiferromagnetic Curie Weiss theta ~ -20 -25 K, with no clear ordering visible susceptibility down to 1.8 K; structure suggest that moments is frustrated by both structural disorder motif.
