Observation of Critical Magnetic Behavior in 2D Carbon based composites
Two dimensional (2D) carbonaceous materials such as graphene and its derivative, e.g., graphydine have enormous potential probability in the major field of scientific research. Theoretically, it has been proposed that the perfect atomic lattice arrangement of these materials is responsible for their outstanding physical and chemical properties even though for poor magnetic properties. Experimentally, it is difficult to obtain the perfect atomic lattice of carbon atom due to the appearance of structural disorders. These structural disorders are generated during the growth or synthesis of carbon-related materials. Investigation of structural disorder reveals that these have some advantages and disadvantages depending on the application. For instance, this disorder reduces the thermal, mechanical stability, and deteriorate the performance of 2D carbon-based electronics devices. While the most interesting role of the structural disorder can be seen in the field of magnetism. Disorders not only create the magnetic ordering within 2D carbon materials but also influence the local electronic structure that opens up the door for future spintronics devices. Although various studies on disorder induced magnetism of 2D carbon materials are available in the literature, still some part of the above field has not been fully exploited. This review presents at putting existing work for the future development of 2D carbon-based devices.
