{sup 75}As NMR and XRD Study of Structural and Electronic Inhomogeneities in Ba(Fe{sub 1−x}Ni{sub x}){sub 2}As{sub 2}
We have used {sup 75}As NMR and x-ray diffraction analysis to study the structural and electronic inhomogeneities in Ba(Fe{sub 1−x}Ni{sub x}){sub 2}As{sub 2} crystals with x near the border of the antiferromagnetic domain.

| description | We have used {sup 75}As NMR and x-ray diffraction analysis to study the structural and electronic inhomogeneities in Ba(Fe{sub 1−x}Ni{sub x}){sub 2}As{sub 2} crystals with x near the border of the antiferromagnetic domain. Unequal nickel population of the equivalent Fe planes and rather homogeneous distribution of Ni inside the planes have been found in the well-ordered single crystal with x = 0.036. Below 40 K a signal wipeout of {sup 75}As NMR spectra is observed for the crystals with x = 0.036 and 0.037. This fact together with spin-lattice relaxation peculiarities is treated a result of the system glassy behavior in this region of the phase diagram. The {sup 75}As NMR data also indicate on partial suppression of antiferromagnetic spin fluctuations around the Ni impurity in these crystals at low temperatures. |
