A detailed investigation on the structural and magnetotransport properties of iron‐intercalated Bi2Se3 single crystals is 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 (MR) shows the non‐saturating linear behavior at higher magnetic field and low temperature. Intercalation of Fe increases the onset of the linear MR behavior, indicating the reduction in quantum effects. The Kohler scaling used on the MR data indicates single scattering process for all these compounds in the measured temperature range of 3–300 K.

铁嵌入Bi 2 Se 3单晶的结构和磁输运研究
详细介绍了铁嵌入的Bi 2 Se 3单晶的结构和磁输运性质。X射线衍射和拉曼研究证实了铁在层间范德华缝隙中的嵌入。化合物的电阻率在插层时降低，并且霍尔电阻率显示出在插层时电荷载流子的增强。磁阻（MR）在较高的磁场和较低的温度下显示出非饱和线性行为。Fe的插入增加了线性MR行为的开始，表明量子效应的降低。MR数据上使用的科勒标度表明，在3–300 K的测量温度范围内，所有这些化合物均经历了一次散射过程。
