Pressure-induced superconductivity in polycrystalline La3Ni2O7
Gang Wang, Ningning Wang, Jun Hou +15
We synthesized polycrystalline La3Ni2O7 samples by using the sol-gel method without post-annealing under high oxygen pressure, and then measured temperature-dependent resistivity u…
Magnetotransport properties of the new-type topological semimetal ZrTe
W. L. Zhu, J. B. He, S. Zhang +4
We report the first experimental results of the magnetoresistance, Hall effect, and quantum Shubnikov-de Haas oscillations on single crystals of ZrTe, which was recently predicted…
Magnetotransport properties of the triply degenerate node topological semimetal tungsten carbide
J. B. He, D. Chen, W. L. Zhu +4
We report the magnetoresistance (MR), Hall effect, and de Haas-van Alphen (dHvA) effect studies of the single crystals of tungsten carbide, WC, which is predicted to be a new type…
Density effect on critical current density and flux pinning properties of polycrystalline SmFeAsO1-xFx superconductor
Y. Ding, Y. Sun, J. C. Zhuang +3
A series of polycrystalline SmFeAs1-xOx bulks was prepared to systematically investigate the influence of sample density on flux pinning properties. Different sample densities were…
Multiple superconducting gap and anisotropic spin fluctuations in iron arsenides: Comparison with nickel analog
Z. Li, S. Kawasaki, T. Oka +12
We present extensive 75As NMR and NQR data on the superconducting arsenides PrFeAs0.89F0.11 (Tc=45 K), LaFeAsO0.92F0.08 (Tc=27 K), LiFeAs (Tc = 17 K) and Ba0.72K0.28Fe2As2 (Tc = 31…
Effect of columnar defects on the pinning properties of NdFeAsO0.85 conglomerate particles
J. D. Moore, L. F. Cohen, Y. Yeshurun +12
Oxypnictide superconductor NdFeAsO0.85 sample was irradiated with 2 GeV Ta ions at a fluence of 5x10^10 ions/cm2. High resolution transmission electron microscopy study revealed th…
Integer and half-integer flux-quantum transitions in a niobium/iron-pnictide loop
C. -T. Chen, C. C. Tsuei, M. B. Ketchen +2
The recent discovery of iron-based superconductors challenges the existing paradigm of high-temperature superconductivity. Owing to their unusual multi-orbital band structure, magn…
Thermally activated energy and critical magnetic fields of SmFeAsOF
Y. Z. Zhang, Z. A. Ren, Z. X. Zhao
Thermally activated flux flow and vortex glass transition of recently discovered SmFeAsOF superconductor are studied in magnetic fields up to 9.0 T. The thermally a…
Strong quantum fluctuation of vortices in the new superconductor
H. H. Wen, S. L. Li, Z. W. Zhao +6
By using transport and magnetic measurement, the upper critical field and the irreversibility line has been determined. A big separation between $H_{c2}(0)…
Lower Critical Field at Odds with A S-Wave Superconductivity in The New Superconductor
S. L. Li, H. H. Wen, Z. W. Zhao +6
The lower critical field has been carefully measured on a well shaped cylindrical sample of the new superconductor fabricated by high pressure synthesis. The penet…
