Structural analysis revealed the successful formation of a porous MgB2 structure in the center and a dense circular MgB2 layer surrounding this structure in the designed-IMD wire. Fast transport I-V measurements showed that the designed IMD method increased engineering critical current density (J e) up to twice that of the IMD wires in self-field. The central porous MgB2 structure shared the applied current and indirectly behaved as an internal stabilizer against quench damage at high applied currents. © 2022 IOP Publishing Ltd. info:eu-repo/grantAgreement/ES/DGA/T54-20R info:eu-repo/grantAgreement/ES/MICINN/AEI/PID2020-113034RB-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.6 2022 PHYSICS, CONDENSED MATTER 25 / 67 = 0.373 2022 Q2 T2 PHYSICS, APPLIED 52 / 160 = 0.325 2022 Q2 T1 1.191 2022 Ceramics and Composites 2022 Q1 Condensed Matter Physics 2022 Q1 Metals and Alloys 2022 Q1 Materials Chemistry 2022 Q1 Electrical and Electronic Engineering 2022 Q1 6.0 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Avci, Dogan Karaboga, Firat Aksoy, Canan Gajda, Daniel Martínez, Elena (orcid)0000-0003-4839-5286 Mehmet Tanyildiz, Fatih Zaleski, Andrzej Babij, Michal Tran, Lan Maria Angurel, Luis Alberto Universidad de Zaragoza (orcid)0000-0001-5685-2366 Fuente, G.F. de la (orcid)0000-0002-0500-1745 Belenli, Ibrahim Belenli 5001 065 Universidad de Zaragoza Dpto.
