Icosahedral symmetry breaking: C_{60} to C_{84}, C_{108} and to related nanotubes

M. Bodner, E. Bourret, J. Patera and M. Szajewska

Synopsis: The structure of a particular type of hollow cage higher fullerenes (C_{60 + N24}) is described and their construction explained from a symmetry breaking mechanism starting from perfect icosahedral symmetry of C_{60} to specific subgroups A_1 \times A_1. This mechanism expands and completes previous results describing the existence of other groups of fullerenes (C_{60 + N10}, C_{60 + N18}) based on the breaking of icosahedral symmetry of C_{60} to the subgroups H_2 and A_2. The mechanism is extended to describe the cases that generate carbon nanotubes.

Magnetic structure determination from the magnetic pair distribution function (mPDF): ground state of MnO

B. A. Frandsen and S. J. L. Billinge

Synopsis: Combined atomic and magnetic pair distribution function refinements have been performed against neutron scattering data from MnO, recovering the expected long-range-ordered antiferromagnetic state and supporting a scenario of monoclinic symmetry on a local length scale of \sim100 Å. This represents the first experimental application of the magnetic PDF method.
