摘　　要：In both the canonical ensemble and grand canonical ensemble,the thermodynamic stability and phase structure of Einstein-Euler-Heisenberg-AdS black holes are studied.We derive the Hawking temperature,Helmholtz free energy,Gibbs potential,entropy and heat capacity of the black holes.We compute the minimum temperature to find that a phase transition may happen at the lowest point.The entropy-temperature diagram consists of two parts.The upper part belonging to the large black holes under the influence from the electromagnetic self-interactions keeps the positive heat capacity,leading the huge compact objects to survive.The lower curves corresponding to small black holes show that the heat capacity of the tiny black holes is negative,which means that the nonlineareffect-corrected smaller sources will evaporate.The further discussions show that the nonlinear effect modifies the thermodynamic quantities,but the corrections limited by the nonlinear factorμwith allowed values can not change the properties and the phase structure fundamentally and thoroughly.We argue that the influence from self-interaction can not make the Einstein-Euler-Heisenberg-AdS black holes to split under the second law of thermodynamics.
