Abstract
A method comprising irradiating a polycrystalline rare earth metal-alkaline earth metal-transition metal-oxide superconductor layer with protons having an energy of 1 to 6 MeV. The irradiating process produces an irradiated layer that comprises randomly dispersed defects with an average diameter in the range of 1-10 nm.
Claims9
A method, comprising:
- irradiating a polycrystalline rare earth metal-alkaline earth metal-transition metal-oxide superconductor layer comprising at least one selected from the group consisting of metal oxide precipitates, columnar defects, and stacking faults with protons having an energy of 1 to 6 MeV, such that the irradiated layer comprises uniformly distributed randomly dispersed defects with an average diameter in the range of 1-10 nm and the at least one selected from the group consisting of metal oxide precipitates, columnar defects, and stacking faults.
