摘要

本研究探讨了铁磁-非磁-铁磁金属三层系统在室温下的传输特性,重点是薄膜平面内的电子电流流动。通过求解玻尔兹曼动力学方程进行分析,探讨了几何随机粗糙度对平行和反平行两种磁性配置下的磁阻效应和电阻率行为的影响。研究还探讨了改变界面化学成分的影响。研究考虑了外表面的两种散射情况:完全镜面散射和完全漫射。研究结果表明,表面质量极大地影响了这些超薄磁层中的电子传输。值得注意的是,在具有光滑界面和完全扩散表面的三层磁层中观察到了最高的磁阻。

Analysis of magnetotransport properties of layered magnetic structures using the Boltzmann approach

Analysis of magnetotransport properties of layered magnetic structures using the Boltzmann approach

The study investigates the transport properties of a ferromagnetic–non-magnetic–ferromagnetic metallic trilayer system at room temperature, focusing on electronic current flow within the plane of the film. The analysis is conducted by solving the Boltzmann kinetic equation to explore the impact of geometric random roughness on the magnetoresistance effect and the resistivity behaviour in two magnetic configurations: parallel and antiparallel. The research also examines the effects of altering the chemical composition of the interfaces. Two scattering scenarios at the outer surfaces are considered: fully specular and fully diffuse. The findings indicate that the quality of the surfaces significantly affects electron transport in these ultra-thin magnetic layers. Notably, the highest magnetoresistance is observed in trilayers with smooth interfaces and completely diffusive surfaces.
