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.
