- We present the experimental evidence for the presence of spinodal decomposition of the magnetic ions in the $Ge_{1-x-y}Cr_{x}Eu_{y}Te$ samples with chemical composition varying in the range of 0.015 ≤ x ≤ 0.057 and 0.003 ≤ y ≤ 0.042. The ferromagnetic transition at temperatures 50 ≤ T ≤ 57 K was observed, independent of the chemical composition. The long-range carrier mediated itinerant magnetic interactions seem to be responsible for the observed ferromagnetic order. The magnetic irreversibility with coercive field $H_C$ = 5 - 63 mT and the saturation magnetization $M_S$ ≈ 2 - 6 emu/g are found to strongly depend on the chemical composition of the alloy.
