New insight into the low temperature phase of Ca<sub>3</sub>Ru<sub>2</sub>O<sub>7</sub>

ORAL

Abstract

Despite the countless theoretical studies on the Ruddlesden-Popper ruthenate Ca3Ru2O7, the structure and physics of its low temperature phase (T < 48 K) remains unclear. Here, using first principle calculations, we shed light on this phase, reconciling several disparate experimental results with a model based on band theory and static correlations. Our results suggest that an accurate description of the strong interplay among electronic correlation, magnetic ordering, spin-orbit interaction, and structural degrees of freedom are necessary to understand the properties of the low temperature phase of Ca3Ru2O7.
