Abstract

The effect of the thulium (Tm) substitution in the Tb₃Al ₅O₁₂, Tb_3-xTm_xAl₅O ₁₂ (TTAG) mixed garnet crystals, has been studied by the solidification of corresponding stoichiometric melts using a micro-pulling down apparatus. The phase composition for the TTAG crystals with different Tm ³⁺ concentrations was determined by powder X-ray diffraction analysis. The amount of the TbAlO₃ perovskite phase in the as-grown TTAG fibers was observed to decrease with substitution of Tm³⁺ in Tb³⁺ site. The lattice parameters of the TTAG were reduced with increase of concentration of Tm³⁺. The results of the Verdet constant measurements are also reported.
