摘要：

The temperature dependence of the Young's modulus E of paramagnetic lutetium has been studied. It has been shown that an important reason for the dependence E(T) is thermal expansion of the crystal lattice, which also leads to a change in the Debye temperature Theta. The effect of this factor is also revealed in the thermodynamic properties of metals. In particular, we have shown that there is another contribution to variation of the total specific heat of lutetium, associated with the Theta(T) dependence and comparable with the electronic contribution.
