Magnetic thin films of cobalt nanocrystals encapsulated in graphite-like carbon

Article Abstract:

The encapsulation of magnetic thin films of cobalt nanocrystals in graphite-like carbon protects air-sensitive magnetic particles against degradation and reduces the magnetic coupling between them. The fabrication process involves co-deposition of cobalt and carbon using ion-beam sputtering and annealing methods. The substrate temperature and the carbon concentration of the Co-C magnetic thin films decides their grain size and the crystal structure. The electron diffraction versus lattice spacing relationship reveals peaks, indicating close packing.

Article Abstract:

The effect of biochar sequestration and the associated bioenergy production on the national and global carbon budgets is examined. Biochar sequestration does not require a fundamental scientific advance, but requires studies to optimize biochar properties and to evaluate the economic costs and benefits for large-scale deployment.
