Thermally stimulated luminescence (TSL) measurements were conducted both on bare substrates and on high-temperature superconducting (HTS) films deposited onto representative substrates, to demonstrate that TSL is applicable to HTS films in detecting

It was recognized shortly after the discovery of high-temperature superconductors (HTS) that these materials would exhibit thermally stimulated luminescence (TSL) as a manifestation of their granularity and consequent inclusion of insulating material

The insulating materials Y2O3, Y2BaCuO5, BaCO3, Ba3CuO4, and BaCuO2, which frequently occur as secondary phases in high temperature superconductors (HTS), have been investigated using thermally stimulated luminescence (TSL). When irradiated with X- o

An increase by over three orders of magnitude from 0.58 mΩ to 1.17 Ω was observed at 4.0 K in the 3 GHz microwave surface resistance of ceramic YBa2Cu3O7−δ following exposure to neutrons. The transport resistivity of an unirradiated pellet was l

Thick (10-15 µm) Tl-Ba-Ca-Cu-O films have been deposited onto yttria-stabilized zirconia and Ag substrates by d.c. magnetron sputtering techniques. Direct deposition onto 1" diameter yttria-stabilized zirconia yields films with typical 22-GHz surfac

We recently demonstrated that insulating surface impurity phases in high‐temperature superconductors can be detected by thermally stimulated luminescence. Moreover, we suggested that the intensity of luminescence is related to the magnitude of the
