Journal ArticleDOI
Defects in correlated metals and superconductors
TL;DR: In this paper, the effect of impurities on local charge and spin degrees of freedom in 1D antiferromagnetically correlated systems was investigated. But the results were limited to the Tc cuprate normal state, which is not soluble in 2 or 3 dimensions and so few exact results are known.
Journal ArticleDOI
Atomic coexistence of superconductivity and incommensurate magnetic order in the pnictide Ba(Fe 1-x Co x ) 2 As 2
TL;DR: In this paper, a Ba(Fe1-xCox)2As2 single crystal for x = 6 was measured in a single crystal with NMR spectra and relaxation rates, and it was shown that all Fe sites experience an incommensurate magnetic ordering below T = 31K.
Journal ArticleDOI
Spinless Impurities in High- T c Cuprates: Kondo-Like Behavior
Julien Bobroff,W. A. MacFarlane,Henri Alloul,Philippe Mendels,N. Blanchard,Gaston Collin,J.-F. Marucco +6 more
TL;DR: In this paper, the effects of spinless impurities on the normal state of high-cuprates were investigated and it was shown that the extra hole introduced by Li is not localized in its vicinity.
Journal ArticleDOI
NMR study in the iron-selenide Rb0.74Fe1.6Se2: determination of the superconducting phase as iron vacancy-free Rb0.3Fe2Se2.
Y. Texier,Joachim Deisenhofer,V. Tsurkan,Alois Loidl,Dmytro S. Inosov,G. Friemel,Julien Bobroff +6 more
TL;DR: The Rb content of the SC phase is deduced from intensity measurements identifying Rb(0.3(1))Fe2Se2 as the actual composition of theSC fraction, bringing this class of superconductors 245 family closer to the other Fe-based superconductor families.
Journal ArticleDOI
Absence of static phase separation in the high T(c) cuprate YBa(2)Cu(3)O(6+y).
Julien Bobroff,Henri Alloul,S. Ouazi,Philippe Mendels,A. V. Mahajan,N. Blanchard,Gaston Collin,V. Guillen,J.-F. Marucco +8 more
TL;DR: It is established that static electronic phase separation is not a generic feature of the cuprates and any large static phase separation between underdoped and optimally doped regions in contrast with the one observed by STM in Bi2212 and by NQR in LaSrCuO.
