Experimental Determination of Thermal Entanglement in Spin Clusters using Magnetic Susceptibility Measurements

A. M. Souza, M. S. Reis, D. O. Soares-Pinto +2

The present work reports an experimental observation of thermal entanglement in a clusterized spin chain formed in the compound Na${}_2$Cu${}_5$Si${}_4$O${}_{14}$. The presence of entangle…
