| Abstract: | The anomalies in electrical transport properties at the displacive phase transition in Pb1?xSnxTe (x=0.18?0.86) has been investigated. The results of applying pressure point out the multiphonon scattering mechanism caused by the soft TO phonons as responsible for the resistivity anomaly. |
