Abstract
We present inelastic neutron scattering experiments of the magnetic excitat ion spectra Of COCl2. 2D(2)O. We find that the excitation energies are well described by the predictions of linear spin-wave theory for a system of we akly coupled ferromagnetic Ising chains. We use the calculated spin-wave in tensities to test the (predicted) existence of magnetic Bloch oscillations in this system. We show that these magnetic Bloch oscillations cannot be ob served in CoCl2. 2D(2)O.
