2D Magnetic heterostructures: spintronics and quantum future

Abstract

AbstractThe discovery of two-dimensional (2D) magnetism within atomically thin structures obtained from layered magnetic crystals has opened up a new realm for exploring magnetic heterostructures. This emerging field provides a foundational platform for investigating unique physical properties and exquisite phenomena at the nanometer and molecular/atomic scales. By engineering 2D interfaces using physical methods and selecting interlayer interactions, we can unlock the potential for extraordinary exchange dynamics, which extends to high-performance and high-density magnetic memory applications, as well as future advancements in neuromorphic and quantum computing. This review delves into recent advances in magnetic 2D materials, elucidates the mechanisms behind 2D interfaces, and highlights the development of 2D devices for spintronics and quantum information processing. Particular focus is placed on 2D magnetic heterostructures with topological properties, promising a resilient and low-error information system. Finally, we discuss the trends of 2D heterostructures for future electronics, considering the challenges and opportunities from physics, material synthesis, and technological perspectives.
