Electronic transport properties of Fe intercalated Bi2Se3 compound: Fe0.10Bi2Se3

We have investigated the electronic transport properties of the Fe intercalated Bi2Se3 single crystals. The electrical resistivity of the compound shows a sharp drop below ∼ 5 K and follows power law (∼Tn) temperature dependence for 6 < T < 50 K with the exponent n = 2.38. The low-temperature heat capacity of the compound shows a peak like anomaly in C/T versus T2 plot near T ∼ 3 K. These results indicate the presence of weak superconductivity in the Fe0.10Bi2Se3 compound at low temperatures.
