cze	Carrier-Mediated Ferromanetism in Vanadium-Doped (Sb1-xBix)2Te3 Solid Solutions	Ferromagnetism in tetradymite-type diluted magnetic semiconductors (Sb1-xBix)1.98V0.02Te3 (0 < x < 1) is revealed to be of hole-mediated nature. The increasing replacement of antimony with bismuth results in a monotonous decrease of the hole concentration and the Curie temperature while the electrical resistivity increases. The value of the Curie temperature shows a linear dependence of N∙p1/3, where N is the vanadium concentration and p is the concentration of hole. This trend agrees with the mean-field theory predictions.
