Abstract

Single crystals of a new diluted magnetic semiconductor Bi2-xFexTe3 (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 Tc 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 = Tc were also observed. The frequency of the de Haas-van Alphen oscillations decreases with increasing x, indicating the donor properties of Fe.
