    A plasma arc reactor for fullerene research (1994)

    Notes: A modified Krätschmer–Huffman reactor for the mass production of fullerenes is presented. Fullerene mass production is fundamental for the synthesis of higher and endohedral fullerenes. The reactor employs mechanisms for continuous graphite-rod feeding and in situ slag removal. Soot collects into a Soxhlet extraction thimble which serves as a fore-line vacuum pump filter, thereby easing fullerene separation from soot. Thermal gravimetric analysis (TGA) for yield determination is reported. This TGA method is faster and uses smaller samples than Soxhlet extraction methods which rely on aromatic solvents. Production of 10 g of soot per hour is readily achieved utilizing this reactor. Fullerene yields of 20% are attained routinely. © 1994 American Institute of Physics.

    Vapor transport growth of C60 crystals (1993)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 62 (1993), S. 531-532

    Notes: A vapor transport technique has been used to produce large, high quality C60 single crystals. This technique, which uses an open tube method with a flowing helium gas carrier, eliminates the crystal size limitation found in the vacuum sublimation growth method.

    Two-dimensional magnetic order of Er in ErBa2Cu3O7 (1990)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Neutron diffraction has been used to study the magnetic order of the Er ions in superconducting ErBa2Cu3O7. Above the three-dimensional (3D) Néel temperature (TN=0.618 K) a rod of scattering characteristic of two-dimensional (2D) behavior is unambiguously observed, showing that the magnetic interactions of the rare earth ions are highly anisotropic, while there are no significant correlations observed between the sheets of Er spins. The system orders two dimensionally, and as a necessary consequence 3D order also sets in at the same temperature. The order parameter is found to obey the exact Onsager solution for a S= (1)/(2) , 2D Ising antiferromagnet. At low T, two separate types of simple 3D antiferromagnetic structures are found, one characterized by a wave vector of ( (1)/(2) , 0,0), and the other by ( (1)/(2) ,0, (1)/(2) ).
