Large Seebeck coefficients in Iron-oxypnictides : a new route towards n-type thermoelectric materials
Loreynne Pinsard-Gaudart, David Berardan, Julien Bobroff +1
The iron-oxypnictide compounds, recently reported as a new class of superconductors when appropriately doped, exhibit large Seebeck coefficients, of the order of -100 microV/K, whi…
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…
Antiferromagnetic properties of a water vapor-inserted compound studied by NMR, NQR and SR
A. V. Dooglav, A. V. Egorov, I. R. Mukhamedshin +10
We present a detailed NQR, NMR and SR study of a magnetic phase obtained during a topotactic chemical reaction of YBaCuO high- temperature superconductor wit…
Correlation length in cuprates deduced from the impurity-induced magnetization
S. Ouazi, J. Bobroff, H. Alloul +1
We report a new multi-nuclei based NMR method which allows us to image the staggered polarization induced by nonmagnetic Li impurities in underdoped O6.6 and slightly overdoped O7…
Reply to the comment of Tallon et al. Cond-Mat/0008295 about Phys. Rev. Lett. 83, 4381 (1999)
J. Bobroff, W. A. MacFarlane, H. Alloul +1
It is shown both from a qualitative and quantitative analysis that the T-dependence of the pure susceptibility detected by Tallon et al. in overdoped compounds cannot explain the T…
