Abstract

We report experimental data about the influence of Fe and Zn substitution on the Tc of YBa2Cu4O8. Dopant occupation sites have been found using Mössbauer spectroscopy for Fe and by x-ray diffraction for Zn. The Fe atoms were found to occupy the Cu(1) site predominantly at low concentration, whereas the Zn atoms possibly reside in the Cu(2) site. Both dopants suppress Tc at the same rate of 23 K/at.% and this phenomenon is completely different from that observed in the YBa2Cu3O7 system.
