Microscopic Charge Inhomogeneities in Underdoped La2 xSrxCuO4: Local Structural Evidence
We present local structural evidence for the existence of charge inhomogeneities at low temperature in underdoped and optimally doped La2 xSrxCuO4. The inhomogeneities disappear for x 0.2. The evidence for the charge inhomogeneities comes from an anomalous increase in the inplane Cu–O bond length distribution in the underdoped samples as well as evidence for CuO6 octahedral tilt inhomogeneities...
متن کاملMagnetic correlations in La2-xSrxCoO4 studied by neutron scattering: possible evidence for stripe phases.
Spin correlations in La2-xSrxCoO4 (0.3 < or = x < or = 0.6) have been studied by neutron scattering. The commensurate antiferromagnetic order of La2CoO4 persists in a very short range up to a Sr content of x = 0.3, whereas small amounts of Sr suppress commensurate antiferromagnetism in cuprates and in nickelates. La2-xSrxCoO4 with x > 0.3 exhibits incommensurate spin ordering with the modulatio...
متن کاملExploring intertwined orders in cuprate superconductors
The concept of intertwined orders has been introduced to describe the cooperative relationship between antiferromagnetic spin correlations and electron (or hole) pair correlations that develop in copper-oxide superconductors. This contrasts with systems in which, for example, charge-density-wave (CDW) order competes for Fermi surface area with superconductivity. La2−xBaxCuO4 with x = 0.125 prov...
متن کاملElectronic self-organization in the single-layer manganite Pr1-xCa1+xMnO4.
We use neutron scattering to investigate the doping evolution of the magnetic correlations in the single-layer manganite Pr1-xCa1+xMnO4, away from the x=0.5 composition where the CE-type commensurate antiferromagnetic (AF) structure is stable. We find that short-range incommensurate spin correlations develop as the system is electron doped (x<0.5), which coexist with the CE-type AF order. This ...
متن کاملSpin and charge orders and their hole - doping dependence in single layered cobaltate
Neutron scattering experiments were performed on single crystals of layered cobalt-oxides La2−xCaxCoO4 (LCCO) to characterize the charge and spin orders in a wide hole-doping range of 0.3x0.8. For a commensurate value of x=0.5 in (H,0,L) plane, two types of superlattice reflections concomitantly appear at low temperature; one corresponds to a checkerboard charge ordered pattern of Co/Co ions an...
