Abstract: The thermal conductivity of CsGd(MoO<subscript>4</subscript>)<subscript>2</subscript> has been studied in the temperature range from 2 to 50 K in zero magnetic field. The analysis of the data performed within the Debye model with the relaxation-time approximation revealed the presence of the scattering of phonons by critical fluctuations. The behaviour of phonon mean free path at the lowest temperatures is discussed. [ABSTRACT FROM AUTHOR]
