We present preliminary studies of magnetic and transport properties of Ge1-x-y Snx Mny Te mixed crystals with 0.091 ≤ x ≤ 0.105 and 0.012 ≤ y ≤ 0.115. Qualitative analysis of our experimental results showed the appearance of a spin-glass phase at T < 50 K. The transport characterization (resistivity and Hall effect measurements) showed that the investigated samples had semimetallic p-type conductivity with relatively large carrier concentrations (p > 1021 cm-3) and low mobilities (μ < 100 cm2 V-1 s-1). The dependence of transport properties on the chemical composition of the samples was observed.
