Abstract
CeO2-doped YBaCuO monoliths synthesized with a top-seeded melt growth process in a conventional box furnace exhibited values of trapped magnetic field of up to 1.33 T at 77 K. To our knowledge, this is the highest value of trapped field reported for a melt-textured YBaCuO monolith. A suitable temperature profile and the use of high-density Y2BaCuO5 substrates led to reproducible single-domain crack-free samples investigated by optical and scanning electron microscopy and trapped field measurements. The zero-field-cooled levitation forces at 77 K of standard samples amounted to 70–83 N. A transport critical current density of up to 1.3 × 105 A/cm2 in self field at 77 K was obtained.
