High-temperature phase transitions in SrBi_2Ta_2O_9 film: a study by THz spectroscopy

F. Kadlec, S. Kamba, P. Kuzel +3

Time-domain THz transmission experiment was performed on a $\mathrm{SrB}{\mathrm{i}}_2\mathrm{T}{\mathrm{a}}_2{\mathrm{O}}_9$ film deposited on sapphire substrate. Temperatures between 300 and 923 K were investigated and comple…
