Abstract

The ferromagnetic phase was found in single crystals of the new diluted magnetic semiconductor of p-Bi₂ - _xFe_xTe₃ (0 ≤ x ≤ 0.08) at a temperature T_c which increases with Fe content x up to T_c = 12 K for x = 0.08. The easy-axis for magnetization is parallel to the C₃ crystallographic axis. In n-type samples Bi₂ - _xFe_xSe₃ ferromagnetic transition was not found down to 2 K. Iron atoms exhibit donor properties. With an increasing the content x of Fe atoms the value of the Seebeck coefficient α increases.
