Pressure effects in the isoelectronic REFe0.85Ir0.15AsO system


Maroni, B; Di Castro, D; Hanfland, M; Boby, J; Vercesi, C; Mozzati, M C; Weyeneth, S; Keller, H; Khasanov, R; Drathen, C; Dore, P; Postorino, P; Malavasi, L (2011). Pressure effects in the isoelectronic REFe0.85Ir0.15AsO system. Journal of the American Chemical Society, 133(10):3252-3255.

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 SmFeAsO(1-x)F(x) series with different doping levels. These results open new questions about the underlying mechanism for superconductivity in iron pnictides.
