Graphene, a single layer of carbon atoms arranged in a hexagonal lattice, has attracted widespread attention for its unique properties as a material. One such property is its magnetic behavior.

In recent years, researchers have found that graphene can exhibit ferromagnetic behavior, meaning it can align itself into a spin-polarized state when subjected to an external magnetic field. This alignment can be useful in applications such as quantum computing and spintronics.
The exact nature of graphene’s ferromagnetic behavior is still being studied, but it is believed to involve the formation of domain walls, which are regions of strong magnetic field where the local spin direction deviates from the global spin direction. The strength and stability of these domain walls depend on several factors, including the thickness and composition of the graphene sheet, the temperature, and the applied magnetic field.
One potential application of graphene’s ferromagnetic behavior is in quantum computing. By controlling the magnetization of graphene, researchers can manipulate its electronic states and perform calculations using qubits. This could potentially lead to more efficient and faster computing capabilities than classical computers.
Another potential use of graphene’s ferromagnetic behavior is in spintronics, which involves the manipulation of magnetic fields using electronic materials. By designing graphene with specific magnetic properties, researchers could develop new devices for energy storage, spintronic communication, and other applications.
However, there are also challenges associated with graphene’s ferromagnetic behavior. For example, the formation of domain walls can be difficult and slow, making it challenging to control and manipulate the magnetic properties of graphene effectively. Additionally, the high cost of producing graphene sheets may limit the availability of this material for practical applications.
