Thermal conductivity of (Er1−xYx)2Ti2O7 pyrochlore oxide solid solutions
Abstract
The thermal conductivities of pyrochlore oxide solid solutions of general formula (Er1−xYx)2Ti2O7 with 0 ⩽ x ⩽ 1 have been determined for high-quality single crystals aligned along the [110] direction, over the temperature range from 3 to 300 K. Er2Ti2O7 and Y2Ti2O7 are isostructural and Er3+ and Y3+ are within 1% in size, but differ by a factor of about 2 in mass. Therefore, this system allows a clear test of the influence of mass of dopant on …
