This work deals with solutions of the Einstein-Born-Infeld (EBT) theory, that can represent black holes or soliton structures (EBIons). The horizon structure of EBI black hole is analyzed as well as it is tested in the isolated horizon framework recently proposed by Ashtekar, considering a fixed charge and varying BI parameter.
