Possible Superconductivity at 37 K in Graphite-Sulfur Composite

H. P. Yang, H. H. Wen, Z. W. Zhao +1

Sulfur intercalated graphite composites with diamagnetic transitions at 6.7 K and 37 K are prepared. The magnetization hysteresis loops (MHL), Xray diffraction patterns, and resist…

Suppression of Superconducting Critical Current Density by Small Flux Jumps in $M g B_{2}$ Thin Films

Z. W. Zhao, S. L. Li, Y. M. Ni +7

By doing magnetization measurements during magnetic field sweeps on thin films of the new superconductor $M g B_{2}$ , it is found that in a low temperature and low field region small f…

Strong quantum fluctuation of vortices in the new superconductor $M g B_{2}$

H. H. Wen, S. L. Li, Z. W. Zhao +6

By using transport and magnetic measurement, the upper critical field $H_{c 2} (T)$ and the irreversibility line $H_{i r r} (T)$ has been determined. A big separation between $H_{c2}(0)…

Lower Critical Field at Odds with A S-Wave Superconductivity in The New Superconductor $M g B_{2}$

S. L. Li, H. H. Wen, Z. W. Zhao +6

The lower critical field $H_{c 1}$ has been carefully measured on a well shaped cylindrical sample of the new superconductor $M g B_{2}$ fabricated by high pressure synthesis. The penet…
