Magnetic and electric properties of antimony selenide (Sb2Se3) crystals

The magnetic susceptibility in the three principal crystallographic directions, and the electrical conductivity and thermoelectric power parallel and perpendicular to the basal plane of Sb₂Se₃ single crystals, have been measured over the temperature range 100–550 K. The different results obtained from the magnetic and electric studies have been accounted for on the basis of non-stoichiometry of the compound and localized lone electrons. A hopping mechanism in the higher temperature region simultaneously with impurity excitation is suggested.
