Melt-grown crystals in the Tl-Ca-Ba-Cu-O system with the same structure type can have substantial differences in the superconducting transition, both in width and onset temperature. These differences are attributed to stoichiometry variations arising

Substantial differences in the superconducting transition, both in width and onset temperature, for the same structure-type have been observed in “pseudo-flux” grown crystals in the Tl-Ca-Ba-Cu-O system. These differences have been attributed to

Detailed structure determinations for numerous crystals grown using a “pseudo-flux growth” technique from different initial metal oxide ratios suggest that cation solid solution occurs in a number of Tl-Ca-Ba-Cu-O high-Tc superconductors. Such ca

Crystals of orthorhombic symmetry obtained on evaporation of CS 2 solutions of C 60 contain solvent molecules rather than representing a new lower density form of pure C 60 . Introduction of I 2 into the CS 2 solutions yields containing solid solutio

We report on the rapid thermal processing (RTP) of YBa2Cu3O7 (Y-123) fibers. Unsintered fibers are densified by RTP. We show that fibers which were originally semiconducting and tetragonal before RTP form normal twinned orthorhombic material after pr

Flux motion effects, flow and creep, have been identified as one of the major problem areas in high temperature superconductors. In this paper, we examine these effects in polycrystalline thin films of the Tl-Ca-Ba-Cu-O high temperature superconducto

We have measured the pressure dependence of the superconducting transition temperature (9.4 K) of ${\mathrm{NbB}}_{\mathit{x}}$ with x near 2 by direct comparison with elemental Nb. We find ${\mathit{dT}}_{\mathit{c}}$/dP=0.04 (\ifmmode\pm\else\textp

TlCaBaCuO High temperature superconductors, especially Tl 2 Ca 2 Ba 2 Cu 3 O 10 with a T c of 120K, are of considerable interest for practical applications. Thin films in this system have demonstrated high T c ′s, compositional toleranc

No superconductivity is found in LiPdH x for compositions where the Li to Pd ratio is varied between 1.2 and 0.8 and x →1 in samples loaded with high pressure (to 2.7 kbar) hydrogen at temperatures to 300°C. Measurements were made in situ so that

Photoinduced currents at single crystal α-Fe2O3 anodes have been observed for incident radiation of greater than the band gap energy (Eg = 2.2 eV). The photoresponse was studied at wavelengths from 0.28 to 0.58 μm for various electrolytic solutions
