NMR study of electronic correlations in Mn-doped Ba(Fe1-xCox)2As2 and BaFe(As1-xPx)2
D. LeBoeuf, Y. Texier, M. Boselli +3
We probe the real space electronic response to a local magnetic impurity in isovalent and heterovalent doped BaFe2As2 (122) using Nuclear Magnetic Resonance (NMR). The local moment…
Possible realization of an antiferromagnetic Griffiths phase in Ba[Fe(1-x)Mn(x)](2)As(2)
D. S. Inosov, G. Friemel, J. T. Park +15
We investigate magnetic ordering in metallic Ba[Fe(1-x)Mn(x)](2)As(2) and discuss the unusual magnetic phase, which was recently discovered for Mn concentrations x > 10%. We argue…
Impurity effects in coupled-ladder BiCu2PO6 studied by NMR and quantum Monte Carlo simulations
L. K. Alexander, J. Bobroff, A. V. Mahajan +3
We present a 31P NMR study of the coupled spin 1/2 ladder compound BiCu2PO6. In the pure material, intrinsic susceptibility and dynamics show a spin gap of about . Substitution of…
Absence of large nanoscale electronic inhomogeneities in the Ba(Fe1-xCox)2As2 pnictide
Y. Laplace, J. Bobroff, F. Rullier-Albenque +2
75As NMR and susceptiblity were measured in a Ba(Fe1-xCox)2As2 single crystal for x=6% for various field H values and orientations. The sharpness of the superconducting and magneti…
Supplementary material for "Impurity-induced magnetic order in low dimensional spin gapped materials"
J. Bobroff, N. Laflorencie, L. K. Alexander +3
In this supplementary material, we investigate further the impurity-induced freezing mechanism in a doped system of 3D weakly coupled ladders resembling Bi(CuZn)ZnP…
Defects in correlated metals and superconductors
H. Alloul, J. Bobroff, M. Gabay +1
In materials with strong local Coulomb interactions, simple defects such as atomic substitutions strongly affect both macroscopic and local properties of the system. A nonmagnetic…
