Metallic and magnetic carbon material
A 3-dimensional crystalline carbon material that is magnetic and metallic under ambient conditions is provided. The material, denominated U-carbon, has been synthesized using the molecular precursor, 3, 3-dimethyl-1-butene (C 6 H 12 ). Depending on the atomic connections made between the carbon atoms of the material, U-Carbon forms structures that exhibit semiconducting and nonmagnetic to metallic and ferromagnetic behaviors. The use of selected molecular precursors (such as 3, 3-dimethyl-1-butene C 6 H 12 ) that support crystal growth based on clustered rather than individual atoms is a paradigm shift in materials development. Rationally designed metastable materials with desirable properties, including U-Carbon, can have many scientific and technological applications.
