Abstract
We report new measurements of thermoreflectance spectra of Cr in the paramagnetic and ferromagnetic phases in the 2.5-4 eV region. The spectra obtained with use of unpolarized and circularly polarized light, with and without external magnetic field, allow one to identify the dominating modulation mechanisms: electron-phonon interaction modulation (shift and broadening effects) in the paramagnetic phase, and exchange interaction modulation (splitting effects) in the ferromagnetic phase.
