摘要：

Single-domain crack-free CeO2-doped YBCO monoliths synthesized in a conventional box furnace using a top-seeded-melt-growth process with an optimized time-temperature profile exhibit trapped magnetic fields of up to 1.4 T and self-field critical current densities at 77 K of up to 1.3 x 10(5) A cm(-2). The observed magnetic properties of the samples correlate with the microstructure, which was studied using optical and scanning electron microscopy. With these high quality high temperature superconductor samples a superconducting magnetic bearing for a 2 MW/10 kW h class flywheel energy storage system was designed and has been tested in a model arrangement.
