Abstract

We report Raman scattering experiments on the coupled spin dimer system Tl_1-xK_xCuCl₃ (x = 0, 0.1 and 1). Qualitatively different magnetic excitations are observed as a function of substitution. TlCuCl₃ shows a broadened two-magnon continuum while KCuCl ₃ exhibits a pronounced three-magnon continuum as well. In contrast, for x = 0.1 a quasielastic scattering shows up. With increasing x phonon anomalies including multi-phonon scattering become pronounced. These features suggest an intriguing interplay between delocalized triplets and lattice degrees of freedom.
