Abstract
Magnetic levitation forces and trapped magnetic fields of top-seeded melt growth-processed YBCO superconductors with multiseeding were studied. The number of seeds was varied from one to six. The surface magnetic field of the prepared YBCO samples was dependent on the number of the seeds. The trapped magnetic field of the top surface decreased with increasing the number of the seed. Particularly, it drastically decreased at the YBCO grain boundary, probably due to the weak rink nature of the boundary. The magnetic levitation force also decreased with increasing the number of the seeds, similar to the variation of the surface magnetic field.
