Vy. Bodryakov et al., EFFECT OF THERMAL-EXPANSION ON THE ELASTIC-MODULI AND DEBYE TEMPERATURE OF PARAMAGNETIC LUTETIUM, Physics of the solid state, 40(9), 1998, pp. 1433-1435
The temperature dependence of the Young's modulus E of paramagnetic lu
tetium has been studied. It has been shown that an important reason fo
r the dependence E(T) is thermal expansion of the crystal lattice, whi
ch also leads to a change in the Debye temperature Theta. The effect o
f this factor is also revealed in the thermodynamic properties of meta
ls. 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.
