Study of a copper oxalate 1DHAF chain system

Abstract: One dimensional Heisenberg antiferromagnetic (1DHAF) chain systems continue to attract interest as there are several outstanding questions about the nature of the propagation of spin excitations, whether ballistic or diffusive and, if diffusive, what power law characterises the autocorrelation function. Systematic studies across a range of 1DHAF systems should help to understand these issues. Muon measurements are proposed here to study a copper oxalate 1DHAF system that is formed via Jahn-Teller distortion and orbital ordering of an underlying honeycomb lattice. Zero field studies will be used to search for magnetic ordering at low temperatures due to residual interchain interactions. These interactions may be suppressed by frustration leading to very low ordering temperature and thus a highly ideal 1DHAF. Field dependent studies in the 1DHAF phase will test the propagation mechanism.
