Melt-processed bulk superconductors: Fabrication and characterization for power and space applications
Melt-process bulk superconducting materials based on variations on the base YBa2Cu3O(x) were produced in a variety of shapes and forms. Very high values of both zero-field and high-field magnetization were observed. These are useful for levitation and power applications. Magnetic measurements show that the effects of field direction and intensity, temperature and time are consistent with an aligned grain structure with multiple pinning sites and with models of thermally activated flux motion.
