Abstract

We review our contributions to the understanding of the structure and properties of irradiation defects in the high T(c) superconductor YBa₂Cu₃O(7-x) (YBCO) using several transmission electron microscopy (TEM) techniques. Irradiating particles have included fast neutrons, ions with energies from 50 keV to 2 GeV, MeV protons, and electrons. In much of this work it has been possible to correlate TEM data with that of bulk superconducting property measurements on the same or similar single crystals. This has been valuable to understand some aspects of magnetic vortex pinning by the irradiation defects, and thus the often large enhancements of the critical current density.
