Single crystals of (Yb {sub x}Gd{sub 1-x}){sub 3}Ga{sub 5}O{sub 12} (0.0 {<=} x {<=} 1.0) have been grown by the micro-pulling-down method. Formation of continuous solid solutions with a garnet structure was confirmed. Composition dependence of the lattice constant, thermal diffusivity, specific heat capacity and thermal conductivity was investigated. Assignment of the Yb{sup 3+}-energy levels in Gd{sub 3}Ga{sub 5}O{sub 12}-host lattice has been performed by using absorption, emission and Raman spectroscopy measurements at both, room temperature and at 12 K.
