Abstract

The high TC superconductor Ba2EuCu307±δ with measured Tc=94±2 K was investigated by Mössbauer spectroscopy. It is shown that the material at low temperatures has either a very high Debye temperature θD > 800 K, or it is crystallographically not single phased with one component (87%) with θD = 378±30 K and the other (13%) with θD = 136±13 K.
