✦ Synopsis

New crystal Nd 3+ :YbVO 4 has been successfully grown by using the Czochralski method. The rocking curves from (0 0 4) and (4 0 0) diffraction planes of as-grown Nd 3+ :YbVO 4 crystal were measured by the high-resolution X-ray diffractometer (HRXRD) D5005, and the full-width values at half-maximum were 19.80 00 for (0 0 4) face and 70.92 00 for (4 0 0) face, respectively. The measured effective segregation coefficients were 0.545 for Nd 3+ and near 1 for V 3+ and Yb 3+ by using the X-ray fluorescence method. The density of Nd 3+ :YbVO 4 crystal is also measured. The measured thermal expansion coefficients are a 1 ¼ 2.6 Â 10 À6 K -1 , a 2 ¼ 2.5 Â 10 À6 K -1 , a 3 ¼ 8.7 Â 10 À6 K -1 from 298.15 to 573.15 K along its crystallographic a, b and c axes, respectively. The measured specific heat is 0.45-0.65 J/g Á K in the temperature range from 298.15 to 573.15 K. The thermal diffusion coefficients of Nd:YbVO 4 were measured and the thermal conductivities were also calculated.
