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 NaCuSiO. The presence of entangle…

Spin-waves in a complex magnetic system: nonextensive approach
D. O. Soares-Pinto, M. S. Reis, R. S. Sarthour +1
In this paper we analyze the spin-wave excitations (magnons) of an inhomogeneous spin system within the Boltzmann-Gibbs framework and then connect the results with the nonextensive…
