Detailed neutron diffraction structure analysis of Bi2Sr2CaCu2O8 is reported. The effects of Pb-substitution on Bi2Sr2CaCu2O8 and Bi2Sr2CuO6 are discussed, and magnetization measurement results on...
SPECIFIC HEAT OF (Ce, La) Ru2Si2 AT HIGH MAGNETIC FIELDS (1988)
Fisher, R., Phillips, N., Marcenat, C., Flouquet, J., Haen, P., Lejay, P., ...
Specific heat (C) measurements on Ce1-xLaxRu2Si2 were made in order to observe the change in C on going from a long range magnetically ordered system (x ≥ 0.08) to a paramagnetic system....
THERMAL EXPANSION OF HEAVY-FERMION CeRu2Si2 (1988)
De Visser, A., Haen, P., Lejay, P., Flouquet, J.
The coefficients of linear thermal expansion of single-crystalline samples of the tetragonal heavy-fermion compound CeRu2Si2, and its non-magnetic analog LaRu2Si2, have been measured in the...
High-pressure magnetization of the heavy-Fermion system CeRu2Si 2 . (1988)
Voiron, J., Lejay, P., Haen, P., Flouquet, J.
The low-temperature magnetization of single-crystal CeRu2Si 2 has been investigated under hydrostatic pressures up to 6 kbar. The results reveal an extremely rapid decrease of the magnetic...
INTRINSIC GEOMETRICAL BOUNDARIES FOR THE CRITICAL CURRENTS INSIDE YBa2Cu3O7-x SINGLE CRYSTALS (1988)
Sulpice, A., Lejay, P., Tournier, R., Chaussy, J.
Magnetization curves have been measured on YBa2Cu3O7-x single crystals of various size, and compared with other results published in the literature. The irreversible magnetization does not follow the...
MAGNETIC BEHAVIOR OF TWO SUPERSTRUCTURES OF CeSn3 : Ce2Sn5 AND Ce3Sn71 (1988)
Bonnet, M., Boucherle, J., Givord, F., Lejay, P., Schweizer, J., Stunault, A.
Ce2Sn5 and Ce3Sn7, which are superstructures of CeSn3, present two different Ce sites. One, similar to the Ce site in CeSn3, is non magnetic ; the other is responsible for their magnetic properties,...
