The high sensitivity of this method enables us to detect the refracted light even above the transition point (Tc). The intensity level extends down three orders of magnitude smaller than that caused by the domains below Tc. This implies the embryos of the ferroelastic domains already exist in the high-temperature phase as the inhomogeneous strain field.American Physical Society1994-09-01engjournal articleVoRhttp://hdl.handle.net/2115/6111http://www.aps.org/https://doi.org/10.1103/PhysRevB.50.58341051-8223Physical Review B50958345837https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/6111/1/PRB50.pdfapplication/pdf929.04 KB1994-09-01
