Description
The Raman spectra of Nb3(Al-Ge) with a superconducting-transition temperature of Tsub(c) approx.=20 K were measured over the temperature range from 300 K to 1.8 K. For V3Si, the unfound Fsub(2g) Raman-active phonon has been observed. In Nb3(Al-Ge) the positions of the Esub(g) and Fsub(2g) phonon peaks, as well as their temperature dependences, show similarities, but also some significant differences to the other high Tsub(c) compounds Nb3Sn and V3Si. This behaviour agrees well with a recent theory of the electron-phonon coupling in high Tsub(c) A15 materials. (author)
