The effective magnetic momentum p_{eff} of Gd-impurities in the Pb_{1-x}Sn_{x}Te⟨Gd⟩ crystals as a function of crystal composition x with 0 ≤ x ≤ 0.25 is studied. It is shown that with the increase in tin content in the crystals from 0 to 0.15, p^{2}_{eff}(Gd) increases slowly from 37 to 43. Then p^{2}_{eff}(Gd) increases abruptly to 63 value when x = 0.16±0.01. For subsequent increase x ≥ 0.17 p^{2}_{eff}(Gd) remains constant at 63. Possible reasons of observed changes of p_{eff}(Gd) and possible mechanisms of influence of the Pb_{1-x}Sn_{x}Te crystal field on the effective magnetic momentum value of Gd-impurities in the crystals under study are analysed.
