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.

The Physical Chemistry/Chemical Physics category includes resources on photochemistry, solid state chemistry, kinetics, catalysis, quantum chemistry, surface chemistry, electro-chemistry, chemical thermodynamics, thermo-physics, colloids, fullerenes and zeolites. Resources dealing with (liquid) crystals and crystallography are also included in this category. This category also includes resources on atomic, molecular and chemical physics, which concerns the structure of atoms and molecules, atomic and molecular interactions with radiation, magnetic resonance and relaxation, Mossbauer effect, and atomic and molecular collision processes and interactions.
