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…

Comment on "Localized behavior near the Zn impurity in YBa2Cu4O8 as measured by nuclear quadrupole resonance"
M. -H. Julien, Y. Tokunaga, T. Feher +2
Williams and Kramer [Phys. Rev. B {\bf 64}, 104506 (2001)] have recently argued against the existence of staggered magnetic moments residing on several lattice sites around Zn impu…

Impurity induced Local Magnetism and Density of States in the superconducting state of YBa2Cu3O7
S. Ouazi, J. Bobroff, H. Alloul +6
Oxygen NMR is used to probe the local influence of nonmagnetic Zn and magnetic Ni impurities in the superconducting state of optimally doped high Tc YBa2Cu3O7. Zn and Ni induce a s…
