Abstract
The transport crystal current density Jc has been measured in Bi2Sr2CaCu2Ox single crystals. With a voltage criterion of 1.0 μV/cm, current density measurements yield Jc values ranging from 300 to 1000 A/cm2 at 77 K and zero field, depending upon crystal quality. The crystals are grown by using a flux method and have a typical size of approximately 10×4×1.5 mm. X‐ray diffraction, scanning electron microscopy, electrical resistivity, and magnetization shielding data are reported.Keywords
