Inhomogeneous CuO6 tilt distribution and charge-spin correlations in La2-x-yNdySrxCuO4 around the commensurate hole concentration
(2003) In Physical Review B (Condensed Matter and Materials Physics) 68(5). p.1-052511- Abstract
- Phononic and magnetic Raman scattering are studied in La2-x-yNdySrxCuO4 with three doping concentrations: x1/8, y = 0; x1/8, y = 0.4; and x = 0.01, y = 0. We observe strong disorder in the tilt pattern of the CuO6 octahedra in both the orthorhombic and tetragonal phases that persist down to 10 K and are coupled to bond disorder in the cation layers around 1/8 doping independent of Nd concentration. The weak magnitude of existing charge-spin modulations in the Nd-doped structure does not allow us to detect the specific Raman signatures of lattice dynamics or two-magnon scattering around 2200 cm–1. ©2003 The American Physical Society
