Charge excitations associated with charge stripe order in the 214-type nickelate and superconducting cuprate

S. Wakimoto, H. Kimura, K. Ishii +10

Charge excitations were studied for stipe-ordered 214 compounds, La${}_{5/3}$Sr${}_{1/3}$NiO${}_4$ and 1/8-doped La${}_2$(Ba, Sr)${}_x$CuO${}_4$ using resonant inelastic x-ray scatteri…
