The ac magnetic susceptibility (χ) was measured in the temperature range T = (1.5÷50) K for Pb_{1-x-y}Sn_{y}Mn_{x}Te samples with a composition y = 0.72, x = 0.015÷0.04 and carrier concentrations in the range p = (2.85÷14) × 10^{20} cm^{-3}. The breakdown of ferromagnetism and the formation of a spin glass phase are observed with an increasing carrier concentration. It is experimentally evidenced as continuous deviation of χ(T) from the characteristic critical behavior observed for ferromagnetic samples.
