It is found that an increase in temperature can lead to an enhancement of pairwise entanglement for a certain range of the frustration parameter. We have, also, found that negativity is equal to the half of the concurrence for the model considered here.eninfo:eu-repo/semantics/closedAccessThermal EntanglementAnalyticalEntanglementArticle10.1016/j.physleta.2006.05.0503585-63633672-s2.0-33748197714Q2WOS:000241640800008Q2
