The results of study of Pb influence on high temperature magnetic and thermal properties of the chalcogenides (Pb_ySn_1-y)₂P₂S₆ are presented. The increasing Pb content shifts phase transition to the ferroelectric state at about 337 K towards lower temperatures while magnetic field till 3 T has no influence on this transition. The measured susceptibility and magnetisation data are discussed.
