Title Specific heat of decamethylferrocenium tetracyanoethanide (DMeFc)(TCNE)
Date 1989
Description We report the specific heat C(T) of (DMeFc)(TCNE) for temperatures 3 K < T < 50 K. We observe an anomaly at Tc-4.82 K corresponding to a transition to a three-dimensional (3D) macroscopic ferromagnet. A broad maximum at = 15 K corresponds to an exchange interaction of J = 35 K along the chain axis. We propose a generalized 1D Hubbard Hamiltonian to account for this feature. Below T (c) results are consistent with the opening up of a gap of approximately 2 meV in the spin-wave spectrum due to the anisotropy in the exchange interaction within the 1D chains.
