Abstract

The short- and long-range spin correlations in the quasi-one-dimensional S=(1/2) system (C6D11ND3)CuBr3 (CHAB-D14) have been investigated by (quasi) elastic neutron scattering experiments. The temperature dependence of the sublattice magnetization below TN=1.56 K reflects the presence of ferromagnetic chains in this compound. The intrachain spin correlations in the paramagnetic region show a crossover from isotropic Heisenberg behavior at high temperatures to XY behavior below ~3 K, and are surprisingly well described by a classical spin model.
