摘要
The correlation between the local current distribution and the microstructure of different types of grain boundaries in YBaCuO monoliths is investigated by magneto-optical technique and inversion of Biot-Savart's law. The grain boundaries (GB's) are formed by a multi-seeding melt-growth process and bonding of monoliths by annealing two monoliths at an external pressure with and without chemical additions.
