Abstract

The discovery of ceramic superconductors with Tc above 77 K has opened up a wide variety of applications for superconductivity. Unfortunately, the use of these ceramics is limited by their inherent brittleness and chemical instability. To circumvent these limitations, a composite approach is being investigated. Glass-bonded 0-3 composites have been formed using YBa2Cu3O7 as a filler. Although these composites do not show zero resistivity, the diamagnetic characteristics of the superconducting filler is preserved. These composites show large diamagnetic susceptibilities and the ability to levitate by repelling magnetic flux.
