International audience ; We present the electrical conductivity measurements of La3Ga5.5Ta0.5O14 (LGT) crystals grown by Czochralski (Cz) technique in Ir crucibles and N2 atmosphere containing few percent of O2. In addition, we have studied the effect of thermal annealing on the stability and the thermal conductivity. The electrical conductivity depends on the stoichiometry, the inhomogeneous impurities levels, the growth atmosphere and the post-growth annealing conditions. Furthermore, we recorded the UV–Vis transmission spectra of the LGT samples and we note that the less resistive LGT samples have an edge of the intrinsic absorption at the highest wavelengths.
