Golub, L. E., & Ivchenko, E. L. (2024). Hanle effect in current induced spin orientation. arXiv preprint arXiv:2410.02947.
This research paper investigates the Hanle effect in current-induced spin orientation (CISP) within two-dimensional (2D) materials, specifically focusing on how the type of electron scattering influences this phenomenon.
The authors develop a kinetic theory framework based on the Boltzmann kinetic equation with a spin-dependent distribution function and collision integral. This framework allows them to analyze the impact of different scattering mechanisms on the Hanle effect in CISP. They apply this theory to two specific 2D systems: 2DEG with parabolic energy dispersion and spin-orbit coupled graphene with linear dispersion.
The study demonstrates that the type of electron scattering is a crucial factor determining the presence and behavior of the Hanle effect in CISP for different 2D materials. This finding has significant implications for the development of spintronic devices based on these materials.
This research provides a comprehensive theoretical framework for understanding the interplay between spin-orbit coupling, magnetization, and electron scattering in determining the spin polarization of 2D materials. This understanding is crucial for advancing the field of spintronics and designing efficient spin-based devices.
The study focuses on the elastic scattering regime and does not consider inelastic scattering processes. Future research could explore the role of inelastic scattering and energy relaxation on the Hanle effect in CISP. Additionally, extending the analysis to other 2D materials beyond 2DEG and graphene would be beneficial.
