CeRhIn 5 is a heavy fermion antiferromagnet that orders at 3.8 K. The observation of pressure-induced superconductivity in CeRhIn 5 at a very high T C of 2.1 K for heavy fermion materials has led to speculations regardingits magnetic fluctuation spectrum. Using magnetic neutron scattering, we report anisotropic three-dimensional antiferromagnetic fluctuations with an energy scale of less than 1.7 meV for temperatures as high as 3T C . In addition, the effect of the magnetic fluctuations on…
