Magnetic phase diagram of the S=1/2 triangular layered compound NaNiO2: a single crystal study
Sophie De Brion, Markus Bonda, Céline Darie +2
Using magnetic torque measurement on a NaNiO2 single crystal, we have established the magnetic phase diagram of this triangular compound. It presents 5 different phases depending o…
Non-magnetic insulator state in Na1CoO2 and phase separation of Na vacancies
C. de Vaulx, M. -H. Julien, C. Berthier +5
Crystallographic, magnetic and NMR properties of a NaxCoO2 single crystal with x~1 are presented. We identify the stoichiometric Na1CoO2 phase, which is shown to be a non-magnetic…
Effect of Sr substitution on superconductivity in Hg2(Ba1-ySry)2YCu2O8-d (part2): bond valence sum approach of the hole distribution
P. Toulemonde, P. Odier, P. Bordet +2
The effects of Sr substitution on superconductivity, and more particulary the changes induced in the hole doping mechanism, were investigated in Hg2(Ba1-ySry)2YCu2O8-d by a "bond v…
Absence of a structural transition up to 40 Gpa in MgB2 and the relevance of magnesium non-stoichiometry
P. Bordet, M. Mezouar, M. Nunez-Regueiro +8
We report measurements on MgB2 up to ~40GPa. Increasing pressure yields a monotonous decrease of the lattice parameters and of the c/a ratio, but no structural transition down to p…
