Numerical calculations of the intrachain dipolar interactions [R. Sessoli and L. Ammannato (unpublished)] in one-dimensional helimagnets show that an (Formula presented)-type anisotropy is favored for sufficiently high values of the helix pitch, i.e., for dominant (Formula presented) antiferromagnetic interaction

More precisely, the paramagnetic contribution was estimated by extrapolating the Curie-Weiss fitting law, valid in the low-temperature range (Formula presented) to the higher temperatures (Formula presented) where the anomaly appears

To obtain the molar specific heat one must observe that a mole of the compound contains (Formula presented) molecules (Formula presented)=Avogadro’s number), thus (Formula presented) spins: (Formula presented) Gd ions and (Formula presented) organic radicals. In the classical limit, each spin contributes to the specific heat with (Formula presented) since it has two degrees of freedom in the Heisenberg model, so that (Formula presented) for (Formula presented)
