Abstract

Single crystals of the new diluted magnetic semiconductor of p-Bi _2-xFe_xTe₃ (0≤x≤0.08) and n-Bi _2-xFe_xSe₃ (0≤x≤0.06) have been synthesized. The ferromagnetic phase was found at a temperature T_c which increases with Fe content x up to T_c = 12 K for x = 0.08 in p-Bi_2-xFe_xTe₃. The easy-axis for magnetization is parallel to the C₃ crystallographic axis. In n-type samples Bi_2-xFe_xSe₃ ferromagnetic transition was not found down to 2 K. The de Haas-van Alphen effect was observed in p-Bi _2-xFe_xTe₃. The Shubnikov-de Haas (SdH) effect was investigated in both types of samples. Frequency of oscillation decreases with Fe doping in p-Bi_2-xFe_xTe₃ and increases in n-Bi_2-xFe_xSe₃. Thus Fe atoms exhibit donor properties.
