Significance Recent intensive investigations have revealed unique electronic transport properties in solids hosting Weyl fermions, which were originally proposed high-energy physics. Up to now, the discovered systems been limited semimetal compounds. Here we demonstrate that elemental semiconductor tellurium is a semiconductor, with typical signatures, including negative longitudinal magnetoresistance, planar Hall effect, as well intriguing logarithmically periodic magneto-oscillations...
We have systematically reported the magnetic and magneto-transport properties of two-dimensional itinerant ferromagnetic compound Fe3GeTe2 at high fields 58 T demonstrated correlation between its transport magnetism. Anomalous two-steps ordering antiferromagnetic-like transitions in zero field-cooling (ZFC) curves for H ∥ ab-plane are observed. Additionally, we find that intrinsic negative magnetoresistances bulk single crystal mainly attributed to suppression spin-fluctuations low fields....
We revisited the anisotropy of heavy-fermion material ${\mathrm{CeCo}}_{2}{\mathrm{Ga}}_{8}$ by measuring electrical resistivity and magnetic susceptibility along all principal $\mathbf{a},\mathbf{b}$, $\mathbf{c}$ axes. Resistivity axis $({\ensuremath{\rho}}_{c})$ shows clear Kondo coherence below about 17 K, while both ${\ensuremath{\rho}}_{a}$ ${\ensuremath{\rho}}_{b}$ remain incoherent down to 2 K. The is well understood within theoretical frame crystalline electric field effect in...
The Ising-like antiferromagnet α-CoV2O6 has received considerable interests because of stabilized 1/3 magnetization plateau around 5 K under magnetic field applied along easy c-axis. In this work, was studied by varying temperature or rotating field. As decreased, collapsed, and additional transitions were observed. a result, rich phase diagram constructed extended to lower than previously reported. When moved from the c b (or a) axis, developed with directions vanished finally when...
An extensive magnetization study in pulsed fields up to 62 T and at temperatures down ~0.7 K has been performed on the single crystals of hexagonal manganite HoMnO3. For magnetic (H) applied along c-axis, successive transitions below 10 a step-like transition ~41 are observed. The phase diagram for H//c is very complex new boundaries explored 6 K. This compared with early results derived from dielectric constant neutron scattering measurements. H//a, two found 3 dome-shaped reported first...
Low-dimensional charge density wave (CDW) systems, which undergo successive so-called Peierls phase transitions at characteristic temperatures associated with corresponding changes in electronic structure, are of great importance for exploring novel quantum physics. Here, we report systematic research the magnetotransport properties quasi-two-dimensional CDW conductor $\ensuremath{\eta}\text{\ensuremath{-}}\mathrm{M}{\mathrm{o}}_{4}{\mathrm{O}}_{11}$ under high magnetic fields up to 59 T....
We present a detailed study of the magnetotransport properties charge density wave state in quasi-two-dimensional purple bronze ${\mathrm{Na}}_{0.9}{\mathrm{Mo}}_{6}{\mathrm{O}}_{17}$ under pulsed fields up to 62 T. Pronounced Shubnikov--de Haas (SdH) oscillations three frequencies have been observed field induced density/spin compound. The two slow are attributed reconstructed electron and hole pockets near ${M}^{\ensuremath{'}}$ point Brillouin zone (BZ). highest-frequency correspond an...
The accommodation of Luttinger liquid behavior and unique quasiparticles in the charge density wave (CDW) state has led to renewed interest low-dimensional molybdenum bronzes. Here, authors report a comprehensive experimental study on quasi-two-dimensional CDW oxide bronzes Mo${}_{4}$O${}_{11}$, which instability is dominated by hidden Fermi surface nesting, resulting magnetic field induced quantum oscillations. Different from monoclinic $\ensuremath{\eta}$ phase, orthorhombic...
