Abstract

Single crystals of a new diluted magnetic semiconductor Bi_2-xFe_xTe₃ (0 ≤ x ≤ 0.08) were grown. For all crystals, the transition into a ferromagnetic state with easy axis parallel to the C₃ axis was observed at temperature T_c increasing with iron concentration and reaching 12 K at x = 0.08. An increase in the Seebeck coefficient, anomalous Hall effect, and resistivity jump at T = T_c were also observed. The frequency of the de Haas-van Alphen oscillations decreases with increasing x, indicating the donor properties of Fe.
