Electronic interaction in the unconventional superconductor Sr2RuO4
Our recent polarized INS experiments on Sr2RuO4 could for the first time quantify the quasiferromagnetic (QFM) fluctuations, which were supposed by to play the essential role in the superconducting pairing of this material. Here we propose to extend these experiments. In particular we need a better characterisation of the magnetic response near the Brillouin zone boundaries including an energy dependency. The suppression of the QFM signal with increasing q is most important to quantify the superconducting pairing and even the latest theoretical approaches find a stronger magnetic signal at the zone boundaries.
