3. Above the transition temperature the magnetic susceptibility of our single crystals is slightly larger than (Formula presented) which is in good agreement with other references.

8. In this context, we particularly refer to recent band-structure calculations that emphasize the crucial role of the lattice degrees of freedom on the electronic properties in (Formula presented) (see Refs. 4 and 5).
9. On the other hand, assuming a conventional electron-phonon interaction for the metallic phase, a coupling constant (Formula presented) can be estimated from transport measurements, but the interpretation suffers from internal inconsistency as shown by P. B. Allen, R. M. Wentzcovitch, W. W. Schulz, and P. C. Cansfield, Phys. Rev. B 48, 4359 (1993).

19. Unfortunately, the elastic shear anisotropy is not fully determined by A for crystal symmetries lower than cubic. In the particular case of tetragonal symmetry a second independent parameter is needed which is usually defined by the ratio (Formula presented) and refers to the anisotropy in the (001) plane. No information on this ratio can be obtained, however, from the present investigation which is restricted to the (110) plane. Thus, only the parameter defined by Eq. (1) can be determined and compared with the corresponding quantity of the reference system (Formula presented)
