Fig. 5. Phase diagram of BKSO and BKBO.

Fig. 5

Red circles are the Tc values of superconductivity (SC) in the antimonates with the same definition as in Fig. 4, and grey triangles are Tc of BKBO (refs. 40,51). Tc values of the antimonates show a half-dome shape (red region), which is similar to that of the bismuthates (dark grey). The crucial difference is that the CDW order in the bismuthates (light grey region) is suppressed at x = 0.4, whereas that of the antimonates (green region) continues to exist up to x = 0.65.
