Magnetization, electrical resistivity, and Hall coefficient of single crystals Sb2-xFexTe3 (0 < x < 0.02) have been measured from 2 to 300 K. Doping diamagnetic Sb2Te3 with Fe results in a paramagnetic behavior and the exchange interaction between Fe ions is determined to be antiferromagnetic based on low-temperature magnetization investigations. We detect no presence of a ferromagnetic ordering in Fe-doped Sb2Te3 down to 2 K. Fe doping initially increases the concentration of holes in relation to the case of pure Sb2Te3 but it rapidly saturates. The electrical resistivity increases throughout the temperature range studied on account of enhanced carrier scattering. (c) 2006 American Institute of Physics.
