Finite-temperature Lanczos investigations of anisotropic magnetic ring molecules — •Oliver Wendland and Jürgen Schnack — Bielefeld University, P.O. box 100131, D-33501 Bielefeld

We investigate magnetic properties of even-membered rings built of vanadium(III) with spin s=1. Vanadium(III) ions are known to possess large anisotropies [1]. Thermodynamical observables are obtained by the finite-temperature Lanczos-method (FTLM), which has proven to be rather accurate [2].
