Figure 2: Transport characteristics and phase diagram of BaTi2Pn2O with Pn=As, Sb, Bi.

From: Intra-unit-cell nematic charge order in the titanium-oxypnictide family of superconductors

Figure 2

(a) Electrical resistivity of BaTi2(As1−xSbx)2O, normalized by the room temperature resistivity. Arrows indicate the anomaly discussed in the text. (b) Phase diagram of BaTi2Pn2O shown as a function of Pn3− ionic diameter. Broken lines are guides to the eye. The error bars accompanying the red circles arise from the instrumental low-temperature limit of 1.8 K. Inset: tetragonal crystal structure of BaTi2Pn2O.
