Correia, J G, Capponi, J J, Ctortecka, B, Butz, T, Tröger, W, Araújo, J P, ...
Electric-field gradients on mercury sites of the HgBa2CuO4+delta high-Tc superconductor were measured with the perturbed angular correlation technique and interpreted with ab initio calculations....
Local probing of Hg neighboorhood in $HgBa_{2}CuO_{4+\delta}$ (2001)
Correia, J G, Araújo, J P, Loureiro, S M, Toulemonde, P, Le Floc'h, S, Bordet, P, ...
Electric field gradients (EFG) on mercury sites of the Hg1201 high-TC superconductors were measured with the perturbed angular correlation (PAC) technique. In Hg1201 samples where PAC detects higher...
Magnetic and transport properties of superconducting (YBa2Cu3O7-δ)1-xAgx ceramics (1989)
Laborde, O, Souletie, B, Guillot, M, Capponi, J.J, Lejay, P, Tholence, J.L, ...
The introduction of silver in the intergranular space of YBa2Cu3O7 ceramics improves their normal state electrical and mechanical properties. The authors report a study of such composites of which...
Pavuna, D, Berger, H, Affronte, M, Capponi, J.J, Guillot, M, ...
The authors present electronic properties and critical current densities (jc at 4.2 K, up to 18 T) of (Y1Ba2Cu3O6.9)1-xAgx compounds in which silver fills the intergranular space without reducing Tc...
170Yb Mössbauer study of the crystalline electric field and exchange interaction in YbFe2 (1979)
Meyer, C., Gros, Y., Hartmann-Boutron, F., Capponi, J.J.
The Mössbauer study of 170Yb in YbFe2 was performed in the temperature range 4.2-60 K. The hyperfine spectra are in agreement with an easy direction of the magnetization along [100]. The thermal...
