Figure 5
Bi2Sr2–xLaxCuO6+δ (x = 0.6) Cu L-edge RIXS spectrum at q∥ = 0.635 Å−1 projected along the crystalline a-axis acquired for 10 min using the grating combination of VPG2 and SVLS2 with an energy resolution of 38 meV (Li et al., 2020BB23). The pink dashed line is the elastic peak and the green dashed line is the bond-stretching phonon. The black solid line is a cumulative fit of the components and a linear background from paramagnons.
