Optical studies of the incommensurate charge ordered phase in La1. 775Sr0. 225NiO4
YG Pashkevich, VA Blinkin, VP Gnezdilov… - Physica B: Condensed …, 2000 - Elsevier
Raman light-scattering and optical conductivity measurements of a single crystal of La1.
775Sr0. 225NiO4 which shows incommensurate charge ordering in a stripe phase have
been carried out. The analysis of the positions, shifts and splitting of the phonon lines that
are induced by charge ordering and the comparison with inelastic neutron scattering data
lead to the conclusion that the charges are located on Ni-sites. The lines which appear from
the (ε, ε, 0) point of Brillouin zone give unambiguous evidence of the pinning of stripes to the …
