Magnetic contribution to the specific heat, magnetic susceptibility and Hall effect are experimentally studied in Pb_{1-x-y}Sn_{y}Mn_{x}Te semimagnetic semiconductors with y=0.72 and x=0.08 and with different carrier concentrations 10^{20} ≤ p ≤ 10^{21} cm^{-3}. The ferromagnetism observed in crystals with p ≥ 3×10^{20} cm^{-3} breaks down with a decreasing concentration of carriers due to an increasing competition between Ruderman-Kittel-Kasuya-Yoshida and superexchange interactions.
