Popis: We present the studies of structural, magnetotransport, and magnetic properties of Ge _1− _x Eu _x Te bulk crystals with the chemical composition, x , changing from 0.008 to 0.025. For the samples with x > 0.015 the sample synthesis leads to formation of Ge _1− _x Eu _x Te spinodal decompositions with a broad range of chemical contents. The presence of Ge _1− _x Eu _x Te spinodal decompositions is responsible for the antiferromagnetic order in our samples with x > 0.015. For the samples with x
