Impact of gamma and electron irradiations on superconducting properties of Bi1.6Pb0.4Sr2Ca2Cu3O10 (Bi-2223) superconductor

In several studies on the impact of radiation towards superconductor, there were evidences that changes may occur in superconducting properties due to alteration in lattice structure of HTS materials. In this work, the solid-state reaction method was employed in preparing the bulk samples of Bi1.6 P...
