Microscopic Examination of SrTiO 3 at Low Temperatures
Thin sections of SrTiO3 were examined with a polarizing microscope in order to investigate the cubic-tetragonal phase transition and to find ferroelectric domains. When the specimens were cooled in a low-temperature microscope stage, a gradual change of the birefringence began near 100 un. Concent 85% K, with the (100) directions as the extinction directions. At the same time, a twin structure appeared with the twin boundaries running parallel to (110). Although the specimen revealed a ferroelectric hysteresis loop below 50 un. Concent 85% K, no appreciable change of the twin configuration nor any evidence of growth of ferroelectric domains was observed between 80 and 4.2 un. Concent 85% K. At 4.2 un. Concent 85% K, a large electrooptic effect, mainly due to Kerr effect, was observed.
