EFFECT OF DISORDER ON SPIN TRANSPORT IN TOPOLOGICAL NON-TRIVIAL MAGNETIC TEXTURES

Abstract:
Topological non-trivial magnetic textures, such as skyrmions and magnetic domain walls, have emerged as promising candidates for future spintronic devices due to their unique properties and potential applications in information storage and processing. However, the impact of disorder on spin transport in these structures remains a topic of significant interest and investigation.

This abstract presents a comprehensive overview of the effect of disorder on spin transport in topological non-trivial magnetic textures. We explore the fundamental mechanisms underlying spin transport in these structures and discuss how disorder influences their transport properties.

In the presence of disorder, scattering processes can significantly affect the spin dynamics in topological magnetic textures. Disorder-induced scattering can lead to spin relaxation, spin-flip processes, and spin dephasing, which can degrade the efficiency of spin transport and impact the stability of these structures. The interplay between disorder and the topological properties of the magnetic textures adds an additional layer of complexity to their behavior.

We review theoretical and experimental studies investigating the impact of disorder on spin transport in various topological magnetic textures, including skyrmions and domain walls. These studies have employed techniques such as micromagnetic simulations, transport measurements, and spin-pumping experiments to elucidate the disorder-induced effects on spin transport.

Furthermore, we discuss strategies to mitigate the adverse effects of disorder on spin transport in topological magnetic textures. These strategies include engineering the material properties, optimizing the device geometry, and applying external control fields to manipulate the magnetic texture’s stability and enhance spin transport efficiency.

Understanding the effect of disorder on spin transport in topological non-trivial magnetic textures is crucial for the development of reliable and efficient spintronic devices. By gaining insight into the underlying physics and exploring techniques to mitigate disorder-induced effects, we can pave the way for future advancements in spin-based technology and harness the full potential of topological magnetic textures.
