Abstract
We have studied the magnetic field distribution of the stacked two single domain Gd-Ba-Cu-O large bulk superconductors exceeding 140Â mm in diameter, and compared with the distribution of one single domain bulk. The maximum trapped magnetic field of the stacked bulk at 65Â K was 4.3Â T and 5Â T at the surface and at the center of two large bulks respectively, when the bulks were field-cooled in 5Â T. It was found that the magnetic field could reach a longer distance and wider area by increasing the thickness. Therefore, larger and thicker bulk superconductor shows several benefits in terms of practical applications.
