## Abstract

Spin fluctuations were studied over a wide momentum ($\\hbar Q$) and energy ($E$) space in the frustrated $d$-electron heavy-fermion metal LiV$\_2$O$\_4$ by time-of-flight inelastic neutron scattering. We observed the overall $Q$$-$$E$ evolutions near the characteristic $Q=0.6$ {\\AA}$^{-1}$ peak and found another weak broad magnetic peak around 2.4 {\\AA}$^{-1}$. The data are described by a simple response function, a highly itinerant magnetic form factor, and antiferromagnetic short-range spatial correlations, indicating that heavy-fermion formation is attributable to spin-orbit fluctuations with orbital hybridization.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
