Query: Intergranular and intragranular properties of superconducting
  multifilamentary Bi 2223 Ag tapes : comparison of electrical transport and
  magnetic measurement methods   Several experimental techniques have been used in order to characterize the
properties of multifilamentary Bi-2223 / Ag tapes. Pristine samples were
investigated by electrical resistivity, current-voltage characteristics and DC
magnetic moment measurements. Much emphasis is placed on comparing transport
(direct) and magnetic (indirect) methods for determining the critical current
density as well as the irreversibility line and resolving usual lacks of
consistency due to the difference in measurement techniques and data analysis.
The effect of an applied magnetic field, with various strengths and directions,
is also studied and discussed. Next, the same combination of experiments was
performed on bent tapes in order to bring out relevant information regarding
the intergranular coupling. A modified Brandt model taking into account
different types of defects within the superconducting filaments is proposed to
reconciliate magnetic and transport data.
