Abstract

We report zero-field inelastic neutron scattering experiments on a deuterated powder sample of [formula omitted]–acetate consisting of a large number of nominally identical spin-10 magnetic clusters. Our resolution enables us to see a series of peaks corresponding to transitions between the anisotropy levels within the spin-10 manifold. A fit to the spin Hamiltonian [formula omitted] yields an anisotropy constant [formula omitted] and a fourth-order diagonal anisotropy coefficient [formula omitted] (the other terms being negligible). Performed in the absence of a magnetic field, our experiments do not involve the g values as fitting parameters, thereby yielding particularly reliable values of D and A.
