论文摘要
已经提出了对铁插入BI2SE3单晶的结构和磁传输特性的详细研究。 X射线衍射和拉曼研究证实了在层之间的范德华缝隙中Fe的插入。插入时，化合物的电阻率会降低，霍尔电阻率显示插入后电荷载体的增强。磁化率显示在较高磁场和低温下的非饱和线性行为。 FE的插入增加了线性磁阻行为的开始，表明量子效应的减少。在磁磁性数据上采用的Kohler缩放率指示所有这些化合物在3-300 K的测量温度范围内的单个散射过程。
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.
