Novel polymorphic phase of BaCu2As2: impact of flux for new phase formation in crystal growth
Hanlin Wu, Sheng Li, Zheng Wu +6
In this work, we have thoroughly studied the effects of flux composition and temperature on the crystal growth of the BaCu2As2 compound. While Pb and CuAs self-flux produce the wel…
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…
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…
Observation of pseudogap-like feature above Tc in LiFeAs and (Ba0.6K0.4)Fe2As2 by ultrafast optical measurement
Kung-Hsuan Lin, Kuan-Jen Wang, Chung-Chieh Chang +8
We utilize ultrafast optical measurement to study the quasiparticle relaxation in stoichiometric LiFeAs and nearly optimally doped (BaK)Fe2As2 crystals. According to our temperatur…
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…
Weak Coupling BCS-like Superconductivity in the Pnictide Oxide BaNaTiSbO (x=0 and 0.15)
Melissa Gooch, Phuong Doan, Zhongjia Tang +3
We report the results of low-temperature heat capacity measurements of the pnictide oxide superconductor BaTiSbO doped with sodium. The temperature and field dependent heat…
