- Retention of the Tetragonal to Orthorhombic Structural Transition in F-Substituted SmFeAsO: A New Phase Diagram for SmFeAs(O(1-x)F(x)) (literal)
- Abstract
- In this Letter we propose a new phase diagram for the SmFeAsðO1?xFx
Þ system, based on careful
analysis of synchrotron powder diffraction data, SQUID, and muon spin rotation measurements. The
tetragonal to orthorhombic structural transition is slightly affected by F content and is retained for the
superconducting samples, even at optimal doping. These findings relate the AFM transition on a different
ground with respect to the structural one and suggests that orbital ordering could be the driving force for
symmetry breaking. (literal)
