Popis: | A detailed investigation on the structural and magneto-transport properties of iron intercalated Bi2Se3 single crystals have been presented. The x-ray diffraction and Raman studies confirm the intercalation of Fe in the van der Waals gaps between the layers. The electrical resistivity of the compounds decreases upon intercalation, and Hall resistivity shows the enhancement of the charge carriers upon intercalation. The magnetoresistance shows the non-saturating linear behavior at higher magnetic field and low temperature. Intercalation of Fe increases the onset of the linear magnetoresistance behavior, indicating the reduction in quantum effects. The Kohler scaling employed on the magnetoresistance data indicates single scattering process for all these compounds in the measured temperature range of 3- 300 K. 6 pages, 6 figures |
