Autor: A. M. Balagurov, V. Yu. Pomjakushin, C Chaillout-Bougerol, Alexei Zakharov, G.J McIntyre, D. V. Sheptyakov

Publikováno v: Physica C: Superconductivity. 321:103-107

The structure of a La 2 CuO 4+ y single crystal with the excess oxygen content y =0.03 has been studied by means of neutron diffraction at T =13 K. Although the extra oxygen content of y =0.03 is inside the miscibility gap of La 2 CuO 4+ y (0.01 y Cm

Autor: Andrea Gauzzi, R. Masini, C. Chaillout-Bougerol, M. Marezio, G. P. Radaelli, F. Licci

Publikováno v: International Journal of Modern Physics B. 13:967-972

In order to understand the difference between the effects induced by chemical substitutions and those induced by applying mechanical pressure, we synthesised and characterised samples of Y ( Ba 1-x Sr x)2 Cu 3 O 7-d. The structural refinements based

Structural Aspects of the Crystallographic-Magnetic Transition in LaVO3 around 140 K

Autor: Sang-Wook Cheong, A. Santoro, M. Marezio, Qingzhen Huang, Bertram Batlogg, C. S. Oglesby, Pierre Bordet, Hidenori Takagi, C. Chaillout

Publikováno v: Journal of Solid State Chemistry. 106:253-270

The perovskite-like compound LaVO[sub 3] undergoes a crystallographic-antiferromagnetic transition at about 140 K. The structure of LaVO[sub 3] has been determined at room temperature and just above (150 K) and below (100 K) the transition. Synchrotr

The synthesis and characterization of the HgBa2Ca2Cu3O8+δ and HgBa2Ca3Cu4O10+δ phases

Autor: Evgeny V. Antipov, J.J. Capponi, C. Chaillout, M. Marezio, S. N. Putilin, Pierre Bordet, J.L. Tholence, Sergio Paulo Martins Loureiro

Publikováno v: Physica C: Superconductivity. 215:1-10

The third (Hg-1223) and the fourth (Hg-1234) members of the recently-discovered homologous series HgBa2Can−1CunO2n+2+δ have been synthesized by solid state reaction, carried out at 950°C under 50 kbar at different annealing times. These phases ha

Evolution of structure and superconductivity with lithium content in Li1−xTi2O4

Autor: J.J. Capponi, C. Chaillout, Pierre Bordet, A. Sulpice, E. Moshopoulou, B. Souletie

Publikováno v: Journal of Alloys and Compounds. 195:81-84

The superconducting properties and crystal structure of the Li1−xTi2O4 compound have been studied as a function of lithium stoichiometry. We show that the presence of a maximum in the Tc(x) curve is the result of the competition between the effects

Structural analysis of the charge transfer mechanism in the superconducting compounds Pb2Sr2Y1−xCaxCu3O8+δ

Autor: C. Chaillout, J.L. Tholence, J.J. Capponi, Omar Chmaissem, M. Marezio

Publikováno v: Journal of Alloys and Compounds. 195:169-172

Pb 2 Sr 2 Ln 1−x Ca x Cu 3 O 8+δ is one of the copper-based superconductors with high critical temperature. Undoped Pb 2 Sr 2 YCu 3 O 8 is not a superconductor and becomes so when some of the trivalent Y cations are replaced by bivalent Ca cations
