Two-Dimensional Magnetic Materials and Their Applications in Spintronic Devices

Abstract

Two-dimensional (2D) magnetic materials have recently emerged as an exciting class of materials for next-generation spintronic devices. Unlike conventional electronic devices that rely on electron charge, spintronics exploits the spin degree of freedom of electrons to enable faster, more energy-efficient, and non-volatile information processing technologies. The discovery of intrinsic ferromagnetism in atomically thin materials such as CrI₃, Cr₂Ge₂Te₆, and Fe₃GeTe₂ has opened new opportunities for integrating magnetic functionality into nanoscale electronic devices. These materials exhibit unique magnetic, electronic, and optical properties that can be tuned through strain, doping, and external fields. This article reviews the fundamental properties of two-dimensional magnetic materials, their synthesis methods, and their potential applications in spintronic devices including magnetic tunnel junctions, spin filters, and memory systems. The study also discusses current challenges such as material stability, fabrication scalability, and interface engineering. Finally, future prospects of 2D magnetism in quantum technologies and energy-efficient electronics are highlighted
