  • Method for producing formed bodies of high temperature superconductors having high critical currents
    Patent number: 6493411
    Abstract: Thermal neutron irradiation of superconducting body compositions into which Li or B has been incorporated as a unit cell external or internal dopant introduces by the nuclear reaction of the dopant pinning centers which substantially improve the critical current density of the body.
