| Abstract: | The fabrication of large, bulk high temperature superconducting YBCO samples was accomplished by MTG process using a seeding technique. The microstructure of the samples was observed by a polarization microscope. It is found that the samples have controlled orientation and large domains. The magnetic repulsion measurements as a function of distance were carried out. The maximum repulsion between the YBCO sample(29 mm in diameter and 10 urn thick)and a Nd-Fe-B permanent magnet with surface magnetic field of 0. 5 T measured at 77 K was 4. 8 N/cm2. The magnetic levitation on the samples exhibits anisotropic behaviour. |
