摘要：

The temperature dependence of the principal values of the refractive index in Sr1-xCaxTiO3 (x=0.014) has been measured in the 17-275 K range under various conditions of sample illumination with 1.96 eV photons. The spontaneous photorefractive contribution delta n(ph) to the temperature-induced variation of the refractive index of Sr1-xCaxTiO3, which appears after illumination of the sample in the ferrophase (transition temperature T-c=32 K) and persists in the paraphase under heating up to 150 K, has been separated. The photoinduced polarization has been estimated. (C) 1997 American Institute of Physics.
