The microstructure of stoichiometric Bridgman melt-textured YBa2Cu307\_6 was investigated by transmission electron microscopy and electron diffraction. Crystal defects like twins, dislocations, small second-phase inclusions and lattice distortions are observed. The density of the dislocations is ext
Magnetic properties of a melt-textured ErBa2Cu3OT\_6 have been studied. The superconducting properties are much improved over those of the sintered sample. The inductive critical current density has the same order of magnitude as in YBa2Cu307\_a single crystals and has a reduced magnetic field depen
