Abstract

Here we report pressure effects on the superconducting transition temperature (T_c) of the ReFeAsO_0.85 (Re=Sm and Nd) system without fluorine doping. In situ measurements under high pressure showed that T_c of the two compounds decreases monotonously over the pressure range investigated. The pressure coefficients dT_c/dP in SmFeAsO _0.85 and NdFeAsO_0.85 were different, revealing the important influence of the deformation in layers on T_c. Theoretical calculations suggested that the electron density of states decreases with increasing pressure, following the same trend of experimental data.
