Abstract
We examine entanglement of thermal states for spin-12 dimers in external magnetic fields. Entanglement transition in the temperature-magnetic field plane demonstrates a duality in spin-spin interactions. This identifies dual categories of symmetric and anti-symmetric dimers with each category classified into toric entanglement classes. The entanglement transition line is preserved from each toric entanglement class to its dual toric class. The toric classification is an indication of topological nature of the entanglement.
