Abstract :
We have investigated current transport characteristics in a mixed state of Bi-2223/Ag multifilamentary tape by varying the angle between the external magnetic field and the tape surface. It was shown that the so-called glass-liquid transition magnetic field, which is an important parameter for applications of persistent current mode, as well as the critical currents, was dominated by the c-axis component (perpendicular to the tape surface) of the external magnetic field in a wide range of the field direction.
