Relaxation of ultrasound in LuxMn1-xS

Relaxation phenomena are studied in LuxMn1-xS solid solution using ultrasound in the temperature range of 80-500 K. The relaxation time of the ultrasound attenuation coefficient and relaxation maximum are determined. The dependencies of the attenuation coefficient of ultrasound on frequency and intensity are found. The current induced by ultrasound is determined.
