C. Jooss et al., Magneto-optical study of current distributions at grain boundaries in YBaCuO melt-textured monoliths, PHYSICA C, 341, 2000, pp. 1423-1426
The correlation between the local current distribution and the microstructu
re of different types of grain boundaries in YBaCuO monoliths is investigat
ed by magneto-optical technique and inversion of Biot-Savart's law. The gra
in boundaries (GB's) are formed by a multi-seeding melt-growth process and
bonding of monoliths by annealing two monoliths at an external pressure wit
h and without chemical additions.
