This paper presents a microscopic theory of magnetoresistance (MR) in magnetic materials, addressing a complex many-body open-quantum problem. It uses a novel open-quantum-system framework to solve the Liouville-von Neumann equation, providing a deeper understanding of MR by connecting it to spin decoherence and magnetic order parameters. This is significant because it offers a theoretical foundation for interpreting and designing experiments on magnetic materials, potentially leading to advancements in spintronics and related fields.
Key Takeaways
- •Develops a microscopic theory of magnetoresistance within an open-quantum-system framework.
- •Connects MR to spin decoherence, including spin relaxation and dephasing.
- •Links resistance to magnetic order parameters (magnetization, Néel vector).
- •Offers a theoretical basis for understanding and designing experiments on magnetic materials.
