We have studied the magnetic field distribution of the stacked two single domain Gd-Ba-Cu-O large bulk superconductors exceeding 140 mm in diameter, and compared with the distribution of one single domain bulk. The maximum trapped magnetic field of the stacked bulk at 65 K was 4.3 T and 5 T at the surface and at the center of two large bulks respectively, when the bulks were field-cooled in 5 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.
