摘要：

Single crystals of a new diluted magnetic semiconductor Bi2- xFexTe3 (0 less than or equal to x less than or equal to 0.08) were grown. For all crystals, the transition into a ferromagnetic state with easy axis parallel to the C-3 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. (C) 2001 MAIK "Nauka/Interperiodica".
