Carbon nanoclusters produced by high-repetition-rate laser ablation of graphite and glassy carbon in Ar exhibits para- and ferromagnetic behavior at low temperature. Magnetic susceptibility and electron paramagnetic resonance of carbon nanofoam samples produced at different Ar pressures demonstrate ferromagnetic behaviour at low temperatures. The results show that the degree of remanent order is strongly dependent on the magnetic history, i.e. whether the samples were cooled under zero-field or...[Show more]
