TL;DR
This study uses polarized inelastic neutron scattering to analyze spin fluctuations in Sr2RuO4, revealing anisotropic behavior and challenging previous NMR findings about ferromagnetic fluctuations.
Contribution
It provides the first polarization-resolved measurements of spin fluctuations in Sr2RuO4, showing anisotropy and contradicting earlier NMR results.
Findings
Spin fluctuations are anisotropic with chi_c/chi_ab=2.0 (0.4).
No evidence of Q-independent or nearly-ferromagnetic fluctuations in 4-22 meV.
Results challenge previous NMR interpretations of magnetic behavior.
Abstract
The spin fluctuations in the normal state of the unconventional superconductor Sr2RuO4 have been studied using inelastic neutron scattering with polarization analysis on single crystals. We find that the spin fluctuations are anisotropic with chi_c/chi_ab=2.0 (0.4). No evidence for Q-independent or nearly-ferromagnetic spin fluctuations are found in the energy range 4-22 meV, in contradiction with NMR measurements.
