Heat capacity and thermal expansion of icosahedral lutetium boride LuB66
Journal Article
·
· Journal of Thermal Analysis and Calorimetry
The experimental values of heat capacity and thermal expansion for lutetium boride LuB66 in the temperature range of 2-300 K were analysed in the Debye-Einstein approximation. It was found that the vibration of the boron sub-lattice can be considered within the Debye model with high characteristic temperatures; low-frequency vibration of weakly connected metal atoms is described by the Einstein model.
