Abnormal thermal expansion coefficients in (Nd1−xDyx)2Zr2O7 pyrochlore: The effect of low-lying optical phonons
Chemical doping is a normal strategy to tune thermal expansion coefficient (TEC) of ceramics in engineering applications, but the resultant TEC values usually follow Vegard’s law, as doping does not modify the nature of chemical bonding in ceramics and its anharmonicity. In this paper, we report abn...
