Equation of state, refractive index and sound velocity of tetragonal Ti-bearing calcium perovskite

The "XRD-DATA" folder contains the raw XRD patterns recorded at each pressure step for the sample and Pt. The "XRD-data.xlsx" summarizes the processed experimental data, including the unit-cell volume of Pt, the calculated pressure and lattice parameters of the sample. Please note that the pressure in the sample chamber of DAC is calculated by means of the equation of state proposed by Fei et al. (2007).The "TDBS-DATA" folder contains the raw TDBS signals recorded at each pressure step for the sample. TDBS signals have been collected from typically two or three different sample positions for each pressure point. Please note that each ".txt" file contains two columns of data, the first column is pump-probe delay time in picosecond, the second column is the relative change of reflectivity.The "TDBS-data.xlsx" summarizes the processed experimental data, as well as the refractive indexes and accordingly the derived longitudinal velocities.
