Trapped magnetic field profiles of arrays of (Gd,Y)Ba2Cu3Oxsuperconductor tape in different stacking configurations

Trapped magnetic field profiles were investigated in thin film (Gd,Y)Ba2Cu3Ox superconducting tapes stacked in different configurations consisting of three 12 mm wide, 36 mm long tapes per layer. The trapped magnetic field values were found to increase monotonically with the increasing number of tape layers in the stack. A crisscross arrangement of the tapes was found to yield a more uniform trapped-field profile than a straight arrangement of the tapes. Furthermore, the decay rate of the trapped magnetic field as a function of distance from the tape stack surface was found to be lower in the crisscross arrangement.
