Abstract
The sound velocities in K 2 PbCu(NO 2 ) 6 were measured in the vicinity of its structural phase transition point of 281 K. The velocity of the transverse sound wave traveling along the [110] direction with the polarization vector in the [1\bar10] direction was found to follow the Curie-Weiss type law; V T [110] = V 0 T [110] - V 1 T [110] ( T 0 /( T - T 0 )), where V 0 T [110] =1.13×10 3 m/sec, V 1 T [110] =2.52×10 2 m/sec and T 0 =172.8 K. The anomalous behavior in the sound velocity was atrributed to the linear coupling between the strain and one of the order parameters associated with local distortion.
