对自旋三重态超导体Sr 2 RuO 4 的单晶进行了非弹性中子散射测量。在正常相和超导相中都观察到了不相称的自旋涨落，并且在 T c 之下和之上具有相同的强度。沿 c 轴磁散射的波矢量依赖性的测量表明 Ru 形状因子的流动特征和各向同性磁化率。
Inelastic-neutron-scattering measurements have been performed on single crystals of the spin-triplet superconductor Sr 2 RuO 4 . Incommensurate spin fluctuations were observed in both the normal and superconducting phases with the same intensity below and above T c . Measurements of the wave-vector dependence of the magnetic scattering along the c axis suggest an itinerant character of the Ru form factor and an isotropic susceptibility.
