Researchers in China have achieved ferromagnetism in graphitic carbon nitride, g-C3N4, by introducing hydrogen dangling bonds into its two-dimensional structure, making the material suitable for spintronic devices.
Spintronics exploits the intrinsic spin of electrons and their associated magnetic moments and charges to make solid-state devices such as storage media and sensors. Generally, the materials used to make these devices are ferromagnetic, that is, they form permanent magnets. Ultrathin 2D nanosheets can be used to construct such devices because they exhibit spin ordering within their structures.
