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.
