Abstract
We present the anisotropy of current transport characteristics in Bi-2223/A g multifilamentary tapes as a function of temperature and external magnetic field. Angular dependence of the critical current and the glass-liquid tra nsition magnetic flux density are well described by the model, taking into account the misorientation of grains with constant effective anisotropy fac tor, gamma. Furthermore, gamma increases apparently as temperature and/or c ritical current increases due to the weak-link properties.
