Magnetic Excitations in Ca3(Ru1-xTix)2O7: Investigating SOC in the 4d-electron ruthenates
Ca3Ru2O7 plays host to a complex interplay between equivalent spin-orbit coupling (SOC) and electron correlation energies that foster exotic physics and an extreme sensitivity to external perturbation. Even with a nominal x=0.003 Ti substitution in
Ca3(Ru1-xTix)2O7 is enough to push the system from a correlated metallic system into a Mott insulating state, concomitant with a magnetic structural transition. Recently we successfully used IN8 with the flatcone detector to map out the inelastic magnetic excitation spectra of Ca3Ru2O7. We now propose to continue our investigation and use IN8 to uncover the underlying changes that arise as the system transitions to the antiferromagnetic Mott insulating state in single crystal Ca3(Ru0.95Ti0.05)2O7.
