Abstract: | Transition metal acetylides, MC2 (M=Fe, Co and Ni), exhibit ferromagnetic behavior of which
TC is characteristic of their size and structure. CoC2 synthesized in anhydrous condition exhibited cubic
structure with disordered C2− 2 orientation. Once being exposed to water (or air), the particles behave
ferromagnetically due to the lengthening of the Co–Co distance by the coordination of water molecules to
Co2+ cations. Heating of these particles induces segregation of metallic cores with carbon mantles. Electron
beam or 193 nm laser beam can produce nanoparticles with metallic cores covered with carbon mantles |
