| Abstract | Neutron diffraction measurements exploring the magnetic and structural phase behaviors of the candidate Jeff=1/2 Mott insulating iridate Sr2IrO4 are presented. Comparisons are drawn between the correlated magnetism in this single-layer system and its bilayer analog Sr 3Ir2O7, where both materials exhibit magnetic domains originating from crystallographic twinning and comparable moment sizes. Weakly temperature-dependent superlattice peaks violating the reported tetragonal space group of Sr2IrO4 are observed, supporting the notion of a lower structural symmetry arising from a high-temperature lattice distortion, and we use this to argue that moments orient along a unique in-plane axis demonstrating an orthorhombic symmetry in the resulting spin structure. Our results demonstrate that the correlated spin order and structural phase behaviors in both single-layer and bilayer Srn+1Ir nO3n+1 systems are remarkably similar and suggest comparable correlation strengths in each system. © 2013 American Physical Society. |
