    Magnetic ordering in the Ising antiferromagnetic pyrochlore Nd 2 ScNbO 7

    The question of structural disorder and its effects on magnetism is relevant to a number of spin liquid candidate materials. Although commonly thought of as a route to spin glass behaviour, here we describe a system in which the structural disorder results in long-range antiferromagnetic order due to local symmetry breaking. Nd2ScNbO7 is shown to have a dispersionless gapped excitation observed in other neodymium pyrochlores below TN = 0.37 K through polarized and inelastic neutron scattering. However the dispersing spin waves are not observed. This excited mode is shown to occur in only 14(2)% of the neodymium ions through spectroscopy and is consistent with total scattering measurements as well as the magnitude of the dynamic moment 0.26(2) μB. The remaining magnetic species order completely into the all-in all-out Ising antiferromagnetic structure. This can be seen as a result of local symmetry breaking due disordered Sc+3 and Nb+5 ions about the A-site. From this work, it has been established that B-site disorder restores the dipole-like behaviour of the Nd+3 ions compared to the Nd2B2O7 parent series

    Metonymy in Language about Organizations: A Corpus-Based Study of Company Names

    In this paper, I examine the use of metonymies in people's talk about organizations. Drawing upon a corpus of natural talk extracted from the British National Corpus (BNC) I identify recurring categories of metonymies that appear to be a central part of people's talk about organizations. These categories of metonymies involve substitutions where an organization stands in for its members, its products, its facilities, its stock or shares or a company-related event. I also found that metonymies in each of these categories are used as basic metonymic expressions that are only partially connected to metaphorical expressions and interpretations of organizations. Where those connections exist, the use of metonymies follows a metaphor-from-metonymy linguistic pattern (where a metaphorical meaning arises from the use of a metonymy) rather than a metonymy-within-metaphor pattern (where a metonymy is part of a metaphorical expression). I elaborate on the implications of these findings for our understanding of how organizations are discursively constructed and understood through metonymic language.
