Abstract

The structural and microstructural properties of the Sm(Fe1-xRux)As(O0.85F0.15) system were investigated by means of high-resolution synchrotron X-ray powder diffraction between 10 K and 300 K. The tetragonal to orthorhombic structural transition temperature decreases with the increase of the Ru content and the symmetry breaking is completely suppressed around x ~ 0.38. By combining the present results with previous magnetic and resistivity measurements, a phase diagram for the Sm(Fe1-xRux)As(O0.85F0.15) system has been drawn.
