A technique based on the presence of an unreacted barium-cuprate phase within the melt-processed microstructure (predominantly at the platelet boundaries), which melts below the peritectic temperature of the YBa2Cu3O7–δ (Y123) phase has been devel

Joining of melt-textured YBa2Cu3O7-δ (Y123) grains has been achieved without use of an external agent. The technique uses barium-cuprate liquid phase released from platelet boundaries to mediate the growth of Y123 at the interface between two grains

Using a magneto-optical (MO) technique, magnetic field distributions have been measured in a melt-textured YBa/sub 2/Cu/sub 3/O/sub 7-x/ bulk superconductor, joined to form an artificial grain boundary (GB), in an external magnetic field perpendicula

Using a magneto-optical technique, magnetic field distributions have been measured in melt-textured YBa2Cu3O7-x, joined to form an artificial grain boundary, in an external magnetic field perpendicular to the sample surface. An inversion scheme using

Large-grain melt-processed YBCO has been joined to create nominally `zero-angle' grain boundaries. Similar broadening of the resistive transition in both grains and the artificial boundary is observed in transport measurements up to 7 T. Direct and p

A technique for joining large-grain YBCO has been used to produce bulk-bicrystal grain boundaries of different orientations. The behaviour of boundaries nominally of 0/spl deg/[100], 0/spl deg/[001] and asymmetric 15/spl deg/[100]-tilt misorientation

We have investigated the superconducting properties of bulk melt-processed YBCO using different experimental techniques. First, single domain materials (i.e. containing no grain boundaries) have been studied. Electrical resistivity, current-voltage c
