Lorenz-Function Enhancement Due to Inelastic Processes near the Néel Point of Chromium

Abstract
We report the discovery of a localized enhancement of the Lorenz function in the vicinity of the Néel point of chromium. It is believed to be a manifestation of the inelastic scattering processes that occur due to the critical fluctuations in the spin-density-wave system resulting in an augmentation of the electron and spin-wave thermal conductivities.
