Weak antilocalization effect due to topological surface states in BiSeTe
K. Shrestha, D. Graf, V. Marinova +2
We have investigated the weak antilocalization (WAL) effect in the p-type BiSeTe topological system. The magnetoconductance shows a cusp-like feature at low mag…
Extremely large non-saturating magnetoresistance and ultrahigh mobility due to topological surface states in metallic Bi2Te3 topological insulator
K. Shrestha, M. Chou, D. Graf +3
Weak antilocalization (WAL) effects in Bi2Te3 single crystals have been investigated at high and low bulk charge carrier concentrations. At low charge carrier density the WAL curve…
Simultaneous detection of quantum oscillations from bulk and topological surface states in metallic Bi2Se2.1Te0.9
Keshav Shrestha, David E. Graf, Vera Marinova +2
Shubnikov-de Haas (SdH) oscillations in metallic Bi2Se2.1Te0.9 are studied in magnetic fields up to 35 Tesla. It is demonstrated that two characteristic frequencies determine the q…
Pressure effects on magnetic ground states in cobalt doped multiferroic MnCoWO
Jinchen Wang, Feng Ye, Songxue Chi +8
Using ambient pressure x-ray and high pressure neutron diffraction, we studied the pressure effect on structural and magnetic properties of multiferroic MnCoWO sing…
Shubnikov-de Haas oscillations from topological surface states of metallic BiSeTe
Keshav Shrestha, Vera Marinova, Bernd Lorenz +1
We have studied the quantum oscillations in the conductivity of metallic, p-type BiSeTe. The dependence of the oscillations on the angle of the magnetic field w…
Superconductivity in titanium-based pnictide oxide compounds
Bernd Lorenz, Arnold M. Guloy, Paul C. W. Chu
Superconductivity in a novel class of layered materials, Ti-based pnictide oxides, was recently discovered. These compounds have attracted interest since they combine features of c…
