摘要：
Quasi-multi layers of Y123/M (M = incomplete oxide layer) are prepared by using pulsed laser deposition. X-ray diffractions indicate that the different growth-controlled precipitates occur inside base films of Y123. In the case of M = YSZ, a heterogenous perovskite phase of BaZrO3, forms as the result of a solid state reaction of YSZ with Y123, leading to T-c obviously decreasing with increasing of M. In the case Of M = Y2O3, however, T-c does not decrease so much. Magneto-transport measurements show the enhanced flux pinning force in high fields for both Y123/Y2O3 and Y123/YSZ, being clearer at lower temperatures. (c) 2007 Elsevier B.V. All rights reserved.
