Abstract
The electron paramagnetic transition of a magnetic ion in light scattering is reported. Intense Raman lines are observed corresponding to the transitions within the Zeeman multiplet of , as well as their combinations with the zone-center longitudinal-optical phonons which interact with band electrons and, in turn, through exchange interaction, with . The phase transition to the magnetically ordered low-temperature phase is manifested in the evolution of the paramagnetic transition into a magnon line.
