Authors studied the remanent magnetic flux distribution in bulk melt-textured YBa2Cu3O7-d (YBCO) crystals after their magnetization in quasi-static and pulsed magnetic fields up to 6 T. Provided the magnetic pulse is sharp enough and its amplitude exceeds twice the penetration magnetic field, the pulse magnetization technique becomes sensitive to sample inhomogeneities. Using this method with appropriate parameters of the magnetic pulse, authors demonstrated that the growth of YBCO crystals in the growth sectors respond to a macroscopic arrangement of weak links. 14 refs.
