Continuation: Magnetic Excitations in doped Ca3Ru2O7 - Investigating the role of SOC in the 4d-electron ruthenates

DOI

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=0.02 Ti substitution in Ca3Ru2-xTixO7 is enough to push the system from a correlated metallic system into a Mott insulating state, concomitant with a magnetic structural transition. We have performed several experiments on the system and found anti-ferromagnetic spin waves and a non-dispersive excitation at 20meV at the magnetic ordering vector.To investigate this feature closer a high-statistics dataset with a large volume in reciprocal space is required.We propose to perform an INS experiment using the MERLIN spectrometer. It is optimized for highest neuton flux in the regime and its updated electronics will overcome previously encountered saturation effects.
