Abstract

Molecular nanomagnets are widely engineerable, low-dimensional spin systems, and typically exhibit strongly correlated ground states. This makes them an ideal playground for investigating quantum entanglement. Here, we present a theoretical investigation of entanglement in a relevant class of nanomagntes, namely the Cr-based wheels. We use exchange energy as a simple means for detecting spin-pair and multi-spin entanglement, and derive the temperature range where such correlations are present in the equilibrium state of the molecules.
