Evidence of magnetic correlations among the charge stripe electrons of charge-stripe ordered La2NiO4.11

Abstract:

The magnetic excitations of charge-stripe ordered La2NiO 4.11 where investigated using polarized- and unpolarized-neutron scattering to determine the magnetic excitations of the charge stripe electrons. We observed a magnetic excitation mode consistent with the gapped quasi-one-dimensional antiferromagnetic correlations of the charge stripe electrons previously observed in La2-xSrxNiO4 x = 1/3 and x = 0.275.

Abstract:

Co-existence of superconductivity and magnetism has been reported in certain regions of the Fe(Se,Te) phase diagram. Here, we address the key question of whether these different properties occur simultaneously within a homogeneous crystal or whether a two-phase description is more appropriate. Extensive microstructural analysis suggests that a Te-rich sample exhibiting both bulk superconductivity and magnetic order contains significant chemical and structural inhomogeneity, suggesting that the two-phase explanation may be valid in this sample. The high-resolution electron backscatter diffraction (HR-EBSD) technique has been used to map local changes in lattice parameter very precisely in these compounds. © 2011 American Institute of Physics.
