“…This behavior implied at once that the dielectric properties of the carbon nanofoam are different from those of carbon aerogels and other carbon nanometer-size porous structures. [39][40][41] This difference can be attributed to the formation conditions: the foam clusters are formed in a very high temperature environment of partially ionized carbon plasma. 38 The carbon nanofoam has a significant sp 3 / ͑sp 2 + sp 3 ͒ bonding ratio of 35% on average, and up to 60% in some regions.…”

We report production of nanostructured magnetic carbon foam by a high-repetition-rate, high-power laser ablation of glassy carbon in Ar atmosphere. A combination of characterization techniques revealed that the system contains both sp 2 and sp 3 bonded carbon atoms. The material is a form of carbon containing graphitelike sheets with hyperbolic curvature, as proposed for "schwarzite." The foam exhibits ferromagnetic-like behavior up to 90 K, with a narrow hysteresis curve and a high saturation magnetization. Such magnetic properties are very unusual for a carbon allotrope. Detailed analysis excludes impurities as the origin of the magnetic signal. We postulate that localized unpaired spins occur because of topological and bonding defects associated with the sheet curvature, and that these spins are stabilized due to the steric protection offered by the convoluted sheets.

“…CAs are novel mesoporous carbon materials with many interesting properties, such as low mass densities, continuous porosities, high surface areas, great mesopore volume and high electrical conductivity [15,16]. These properties are derived from their three-dimensional nano-network structures.…”

“…In addition to graphite, sp 2 -bonded carbon in form of onions, ribbons, nanotubes and fullerenes can be synthesized. The formation of enclosed structures eliminates the dangling bonds and thereby reduces the total energy of the carbon atoms in the structure [3].…”
