TL;DR: The nuclear spin-lattice relaxation times of 1H and 133Cs in CsFeCl3.2H2O and RbFeClCl3 as discussed by the authors are measured in the paramagnetic region and can be satisfactorily described with a diffusive soliton model.
Abstract: The nuclear spin-lattice relaxation times of 1H and 133Cs in CsFeCl3.2H2O and RbFeCl3.2H2O are measured in the paramagnetic region. Both relaxation rates have an activation-type temperature dependence in a wide temperature range together with a maximum at a temperature well above the zero-field 3d-ordering temperature. This behaviour can be satisfactorily described with a diffusive soliton model.

TL;DR: In this paper, the spin dynamics of a quasi-one-dimensional ferromagnetic Ising system (CH3)3NH.CoCl3.2H2O (TN=4.135K) were studied by measuring the proton spin-lattice relaxation rate at 3-300K in externally applied fields of 2.5-33 kOe parallel to the Ising axis.
Abstract: The spin dynamics of a quasi-one-dimensional ferromagnetic Ising system (CH3)3NH.CoCl3.2H2O (TN=4.135K) is studied by measuring the proton spin-lattice relaxation rate at 3-300K in externally applied fields of 2.5-33 kOe parallel to the Ising axis. The overall behaviour of the temperature and field dependence including a rate maximum at a temperature well above TN is found to be governed by the q to O and omega to 0 component of the susceptibility.
