Abstract

The Cu3Fe0.5Se2 crystals are grown by substitution a part of Cu with Fe atoms, structure and cell parameters of this crystal are specified as: Orhorhombic with a=8169; b=8238; c=12052 Å; and V=811.15 Å3, Dx=6,23 g/cm3, Sp.Gr.Pnma, Z=8. The magnetic succeptibility of this crystal is measred in the temperature range of 100°K<T<400 °K, and H=2 Tesla. It is found that below T=350 °K system changes to antiferromagnetic state. Parameters of α, σ and k are obtained in the temperature range of 80 °K <T <400 °K, and is calculated n = 5×1019 cm-3..
