Measurements of static dielectric constants, electrooptic coefficients
, absorption, light-induced absorption, photo and dark conductivity, h
olographic diffraction efficiency and photorefractive two-beam couplin
g gain are performed with a single-crystalline Ba0.984Sr0.016TiO3 samp
le. Crystals of this composition melt congruently and can be grown by
the Czochralski technique. They are very attractive for photorefractiv
e applications.
