Revisiting the spin susceptibility of Sr2RuO4
The superconductivity of Sr2RuO4 HAD been believed to be not a spin singlet but a spin triplet with strong evidences that the NMR knight shift and the polarized neutron scattering measurements revealed a constant spin susceptibility across and well below Tc. In recent years, however, there appear several experimental evidences which support non p-wave symmetry. Moreover, in the beginning of this year, Pustogow et al. arXived that their 17O NMR night shift data clearly shows a drop below Tc, and then Prof. Ishida at Kyoto Univ. admitted that their previous NMR data was misleading due to the heat input by the RF pulses. But the previous polarized neutron results also supported the p-wave scenario since it also shows constant temperature dependence of susceptibility below Tc. This makes us to propose another polarized neutron scattering experiment on Sr2RuO4. In the present study, we want to measure the low-Q ferromagnetic susceptibility by using polarized neutron diffraction technique at D33 with a polarized option. Single crystals of Sr2RuO4 with total mass up to 25g are already available. We request 4 days of beamtime.
