The effect of chemical and hydrostatic pressure has been studied systematically in a selected system belonging to the 1111 family of iron pnictide high-temperature superconductors. The results show a surprising similarity between the trend of critical temperature vs hydrostatic pressure for isoelectronic samples with different rare earths (RE) on the RE site and samples of the SmFeAsO1-xFx series with different doping levels. These results open new questions about the underlying mechanism for superconductivity in iron pnictides.

Abstract
The effect of chemical and hydrostatic pressure has been studied systematically in a selected system belonging to the 1111 family of iron pnictide high-temperature superconductors. The results show a surprising similarity between the trend of critical temperature vs hydrostatic pressure for isoelectronic samples with different rare earths (RE) on the RE site and samples of the SmFeAsO1-xFx series with different doping levels. These results open new questions about the underlying mechanism for superconductivity in iron pnictides.| File | Dimensione | Formato | |
