Carrier-mediated ferromagnetism in vanadium-doped (Sb1−xBix)2Te3(Sb1−xBix)2Te3 solid solutions

Ferromagnetism in tetradymite-type diluted magnetic semiconductors (Sb1−xBix)1.98V0.02Te3(Sb1−xBix)1.98V0.02Te3 (0 ⩽ x ⩽ 1)(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 Np1/3Np1∕3, where NN is the vanadium concentration and pp is the concentration of hole. This trend agrees with the mean-field theory predictions
