Abstract
Quasi-single-crystal specimens were grown from rods of bulk YBa 2Cu3O7-δ by a-melt-textured (MT) growth process. The material´s magnetization was highly anisotropic, which supports the microstructural picture. While M-H data show that there is a high bulk critical current density, the flux creep behavior indicates that pinning in MT material differs little from that in single crystals or grains of sintered material. The anomalous magnetization reported by M. Daeumling et al. (1990) was observed in only one of three samples taken from the same rod
