## Abstract A possible structural change in Sr~0.66~Ba~0.34~Nb~2~O~6~ singleβcrystal fibers when the temperature decreases from 295 to 10 K was investigated by dielectric constant measurements and Raman spectroscopy. An anomaly observed in the dielectric constant and the loss factor is associated w
The birefringence of (Ca 0.28 Ba 0.72 ) 0.75 (Sr 0.60 Ba 0.40 )Nb 2 O 6 crystal is measured basing on polarization-extinction method and conoscopic interference method. Experimental results show that the birefringence in this crystal is up to 10 -5 , the natural birefringence in this crystal is (n o
