Results of investigation of n-type Bi2-xMnxTe3 with x approximate to 0.025 grown by the Bridgman method are presented. Structural properties are studied by means of x-ray diffraction, EDX and positron lifetime spectroscopy. Results of AC magnetic susceptibility measurements and electronic magneto transport measurements show existence of ferromagnetic phase transition at 5.3 K. Effects of the phase transition on the electronic transport properties are studied. (C) 2014 Elsevier B.V. All rights reserved
