Inelastic neutron scattering reveals strong spin fluctuations with energies as high as 0.4 eV in the nearly antiferromagnetic metal Cr0. 95V0.05. The magnetic response is well described by a modified Millis-Monien-Pines function. From the low-energy response, we deduce a large exchange enhancement, more than an order of magnitude larger than the corresponding enhancement of the low-temperature electronic heat capacity gammaT. A scaling relationship between gamma and the inverse of the wave vector-averaged spin relaxation rate gammaave is demonstrated for a number of magnetically correlated metals.
