Flux Pinning Behavior of Incomplete Multilayered Lattice Structures in YBa(2)Cu(3)O(7-d)
Abstract
Magnetization results of YBa(2)Cu(3)O(7-d) films processed with interlayers of CeO2 inclusions are presented. Unexpected flux pinning results that are different from previous observations with nanoparticulate layered inclusions were observed. Flux pinning was found to be in some cases either slightly improved at either low fields <0.5 T or in other cases at high fields >8 T although degraded, sometimes severely, at interim magnetic fields. Most unexpectedly, the pinning performance of the various samples rapidly converges as the temperature is reduced from 77 to 65 K, causing all films to have similar Jc (H) behavior at 65 K even though dramatically different at 77 K.
