Abstract
The temperature dependence of the photoacoustic signal was studied in SbCl5-intercalated graphites characterized by different degrees of ord ering. The measurements were based on piezoelectric photoacoustic dete ction. In the temperature range 200-220 K corresponding to a structura l phase transition in intercalated layers, the amplitude and phase shi ft of the photoacoustic signal reached their maximum values. The incre ase in the photoacoustic amplitude was attributed to the change in the sample volume that occurs in the course of the phase transition.
