Spintronic devices based on two-dimensional magnets

Spintronics, an emerging interdisciplinary field that manipulates spin polarizations and transport processes of electrons, promises a new generation of ultra-low power consumption, high-speed, and highly integrated electronics. Two-dimensional (2D) magnets have emerged as ideal candidates for spintronic applications, owing to their unique characteristics: exceptional sample quality at atomic-scale thickness, atomically smooth interfaces, and the ability to form versatile van der Waals heterostructures. This review summarizes recent advances in spintronic devices based on diverse 2D magnetic configurations, focusing on their architecture design, physical mechanisms, performance, and modulation strategies. We further conclude with a perspective on future research directions in this rapidly evolving field.
