Due to a mistake by the Publisher, in the article mentioned above, the sequence of Figs. 4, 5 and 6 has been changed. The figures should be placed in the following order.

Fig. 4. An image of a region in which the habit plane of a low angle tilt boundary (marked 1M) varies between the (001) planes of the two grains.

Fig. 6. Schematic diagrams of the low angle tilt boundaries shown in Figs. 3 and 5. High-T, ‘pathways’ crossing the boundary plane made up of the (2212) and (2223) phases can be seen. Supercurrents, as labelled, can flow between the grains on the &planes.
