Abstract

We report the observation of the $A_{g}$ -symmetric one-magnon Raman peak in the magnon Bose-Einstein condensation phase of ${TlCuCl}_{3}$ . Its Raman shift traces the one-magnon energy at the magnetic $Γ$ point, and its intensity is proportional to the squared transverse magnetization. The appearance of the one-magnon Raman scattering originates from the exchange magnon Raman process and reflects the change of the magnetic-state symmetry. By using the bond-operator representation, we theoretically clarify the Raman selection rules, which are consistent with the experimental results.
