Abstract

In this work we present galvanomagnetic measurements andRaman scattering spectra of Pb_0.75 Sn_0.25Te + 1.2 at.% In. Positions and concentrations of different In impurity states are obtained using the Gibbs distribution and results of galvanomagnetic measurements. In Raman spectra, modes at about 90, 170, 340, 510 and 570 cm^-1 were observed at all temperatures. These modes were discussed in terms of multiphonon emission (MPE) process on DX-like centers.
