Low-dimensional magnetic systems often provide a wealth of interesting and unexpected phenomena. Some systems have the distinction that they can be used to rigorously test certain exactly solvable hamiltonians, exploring exotic phases as a function of temperature, pressure and magnetic field. Others show that these hamiltonians break down in practice as nonlinear or hidden effects come in to play. We have recently synthesised single crystals of (ND4)3CoCl5, in which the Co 2+ ions form a 1D zig-zag chain, shows a curie-weiss temperature of order 100, and yet does not order until 2.3K, indicating that the interchain interactions are exceedingly weak compared to the intrachain interactions. We wish to characterise the magnetic structure of this material in order to gain some understanding of the potential physics it may exhibit before proceeding to in-field and inelastic studies.
