2026-06-18 Raman spectra data set of the Ba(Ti0.57,Ge0.43)O3 solid solution at high pressures and room temperatureRaman spectra data set of the Ba(Ti0.57,Ge0.43)O3 solid solution at high pressures and room temperature doi:10.57760/sciencedb.40278 en The data set was collected using a WITEC Alpha 300R confocal Raman spectrometer at a wavelength of 532 nm in the hydrothermal laboratory at the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences. A symmetrical diamond anvil cell with a 400 μm mesa was used to create a high-pressure environment. Two sets of data were collected: one set with a test pressure range of 3–30 GPa, with 284 test data points, including 180 ruby test data of pressure and 104 sample test data. The other set of test pressures ranged from 0.1 to 12 GPa, with 174 test data, including 112 ruby data of pressure and 62 sample test data.  high pressure; solid solution; Raman; Ba(TixGe1-x)O3; perovskite structure Lin Sichen Xiao Wansheng Song Maoshuang PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
