Magnetism in low-dimensional carbon materials, which is crucial for the realization of the physical properties, potential application, and development of carbon-based spintronic devices, has attracted extensive attention. In this Review, three typical low-dimensional carbon materials, including carbon nanotubes, graphene, and graphdiyne, are used to exhibit the research progress of a magnetic two-dimensional (2D) carbon material preparation strategy, the introduction of the local magnetic moment, and the resulting unique magnetic properties. The convenient and facile preparation methods of carbon-based magnetic materials have been introduced on the basis of their structural characteristics, especially for the advantageous structures and efficient chemical modification in graphene and graphdiyne. Various interesting ways, such as transition metal atom doping and nonmetal atom modification, have been exhibited to tune the electromagnetic characteristics of carbon-based materials. All those research studies provide a theoretical basis to promote the application of 2D carbon-based magnetic materials in spintronic devices involving spin and charge modulation and lay a foundation for the preparation of high-performance carbon-based magnetic materials with specific magnetic properties.

“…Because of the interfacial proximity effect, magnetic moments can be introduced into 2D nonmagnetic materials, and impressive physical phenomena can appear in the artificial heterostructure, such as magnetic field-dependent anomalous Hall effect 39 and the metal−insulator transition. 40 In addition to magnetic nanoparticle layer, using a nonmagnetic cluster combined with a ferromagnetic electrode can achieve similar modulation of spin-dependent transport, as shown in Figure 5c. 41 The integration of magnetic organic molecules with 2D materials can induce novel in-plane SDTBs in nonmagnetic materials.…”

Spintronics is a promising alternative to the conventional silicon transistor-based electronics that are gradually approaching their physical limitations. Ultrathin two-dimensional van der Waals (vdW) materials (2D materials) with controllable spin degrees of freedom are recognized as extremely promising spintronic materials in architectures for the post-Moore era. In this Perspective, we review recent progress on spin-dependent transport behaviors (SDTBs) confined at the 2D scale, which are the mainstream paradigms for spintronic devices. We first present the mechanism and the key factors of SDTBs in 2D nonmagnetic materials-based hybrid devices. Then, some chemical modulation strategies for inducing short-range magnetic order and magneto-electric performance into 2D nonmagnetic materials are discussed. Furthermore, we concentrate on introducing intriguing SDTBs in 2D long-range ferromagnetic materials-based vdW devices. Finally, we highlight the current challenges in the study of spin-dependent transport of 2D modified materials and 2D material-based spintronic devices, in the hope of accelerating their applications.

Graphene, with spin and valley degrees of freedom, fosters unexpected physical and chemical properties for the realization of next‐generation quantum devices. However, the spin‐symmetry of graphene is rather robustly protected, hampering manipulation of the spin degrees of freedom for the application of spintronic devices such as electric gate‐tunable spin filters. It is demonstrated that a hybrid heterostructure composed of graphene and LaCoO3 epitaxial thin film exhibits an electrically tunable spin‐exchange splitting. The large and adjustable spin‐exchange splitting of 155.9 – 306.5 meV is obtained by the characteristic shifts in both the spin‐symmetry‐broken quantum Hall states and the Shubnikov–de Haas oscillations. Strong hybridization‐induced charge transfer across the hybrid heterointerface has been identified for the observed spin exchange splitting. The substantial and facile controllability of the spin exchange splitting provides an opportunity for spintronics applications with the electrically‐tunable spin polarization in hybrid heterostructures.
