Melt textured YBCO samples for trapped field magnets and levitating bearings
Bulk melt textured YBCO materials in the shape of disks are being developed for use as trapped field magnets and in superconducting bearings. The trapped field in the gap between two disks of 26 mmExpand

Influence of the lateral movement on the levitation and guidance force in the high-temperature superconductor maglev system
After the levitation force relaxation was studied for different field-cooling height and working-levitation height, the high-temperature superconductor (HTS) bulk was horizontally moved in theExpand

Zn doping of YBa2Cu3O7 in melt textured materials: peak effect and high trapped fields
Abstract The previously introduced modified melt crystallization process (MMCP) has been applied to prepare single grain YBCO bulk material with Zn partially substituting for Cu. Hole doping wasExpand

High trapped fields in bulk YBa2Cu3O7−δ samples at temperatures around 50 K
Bulk melt textured YBa2Cu3O7−δ samples with single grains of about 24 mm diameter were obtained by use of SmBa2Cu3O7−x seed crystals. The maximum trapped field B0 in the gap between two samples wasExpand

Multi-seeded melt crystallization of YBCO bulk material for cryogenic applications
YBCO bulk materials were crystallized by a multi-seeded melt growth process. Up to four biaxial oriented Sm-123 seeds were placed on the top of rectangular shaped YBCO bars (up to ). The orientedExpand

Influence of silver addition on cracking in melt-grown YBCO
Abstract The influence of silver addition on a–b microcracking and c-cracking in melt-grown YBa2Cu3O7/Y2BaCuO5 single-grain superconductors of nominal composition YBa2Cu3O7+0.24Y2O3+0.02Pt wasExpand

Superconducting permanent magnets and their application in magnetic levitation
Abstract Superconducting permanent magnets form a completely new class of permanent magnets. Of course, they must be cooled to 77 K or below. At very low temperatures (24 K) their magnetization canExpand
