## Abstract Barium tungstate (BaWO~4~) single crystal has been grown using Czochralski technique. It belongs to the scheelite structure, forming the space group __I__ 4~1~/__a__ at room temperature and the primitive cell contains two molecular units. The polarized Raman spectra were recorded by a m
We have measured the temperature dependence of the thermal conductivity ~b in direction parallel to the copper-oxygen planes for a single crystal of LaLssSr0.1sCuO4-~ in the temperature range from I.gK to 50K. tcab shows the enhancement at the superconducting transition temperature T~. Below 15K, tz
